Section 1—General Information
Introduction
PowerPact® M-frame, P-frame and R-frame and Compact® NS630b–NS3200 electronic trip molded
case circuit breakers are designed to protect electrical systems from damage caused by overloads, short
circuits, and ground faults. All circuit breakers are designed to open and close a circuit by nonautomatic
means and to open the circuit automatically on a predetermined overcurrent. Electronic trip molded case
circuit breakers use an electronic trip system to signal the circuit breaker to open automatically.
The PowerPact M-frame (800 A frame size), P-frame (1200 A frame size) and R-frame (2500 A frame
size) circuit breakers are dual rated to UL489 and IEC 60947-2. The Compact NS630b–NS1600 (1600
A frame size) and NS1600b–NS3200 (3200 A frame) circuit breakers are rated to IEC 60947-2 only.
M-frame molded case circuit breakers are equipped with a basic ET1.0 electronic trip system, which has
a fixed long-time (overload) setting and an adjustable instantaneous (short-circuit) trip setting. P-frame,
R-frame and NS630b–NS3200 molded case circuit breakers are available with either a basic ET 1.0I
electronic trip system or with a more advanced Micrologic® trip system. Electronic trip motor circuit
protectors (trip system ET 1.0M), which trip on short circuit only, and automatic molded case switches,
which trip at a predetermined self-protection level only, are also available for special applications. All of
these circuit breakers are available labeled as Square D® or Schneider Electric (formerly Merlin Gerin,
Federal Pioneer, or Federal Pacific).
For information on other PowerPact molded case circuit breakers manufactured by Square D, see the
Class 611 catalog PowerPact H and J-Frame Circuit Breakers and the Class 616 catalog PowerPact
D-Frame Circuit Breakers.

Circuit Breaker Ratings
Interrupting Rating
The interrupting rating is the highest current at rated voltage the circuit breaker is designed to safely
interrupt under standard test conditions. Circuit breakers must be selected with interrupting ratings equal
to or greater than the available short-circuit current at the point where the circuit breaker is applied to the
system (unless it is a branch device in a series rated combination). Interrupting ratings are shown on the
front of the circuit breaker. For grounded B phase interrupting ratings, see Data Bulletin 2700DB0202.

Application Ratings
The voltage rating is the highest voltage for the electrical system on which the circuit breaker can be
applied. The frequency rating indicates the system frequency for which the circuit breaker is intended.
The withstand rating is used to improve system coordination by maximizing the current level at which
the circuit breaker trips with no intentional delay. The withstand rating is the level of RMS symmetrical
current that a circuit breaker can carry in a closed position for a stated period of time.
Ampere Rating (Continuous Current Rating)
The ampere rating (or continuous current rating) (Ir) is the maximum current that a circuit breaker can
carry. The sensor size (In) is the maximum ampere rating for a specific circuit breaker and is based on
the size of the sensor plug inside the circuit breaker. This value is printed below the trip unit on the
sensor plug. See Sensor Plugs (page 72) for more information.
NOTE: The maximum ampere rating a circuit breaker family can carry is called the frame size. Sensor
size is less than or equal to frame size.
The ampere rating of a type ET electronic trip circuit breaker is equal to the current sensor size (In).
The ampere rating of a Micrologic® electronic trip circuit breaker is determined by the mathematical
equation:
Ampere Rating = Sensor Size x Rating Plug Setting (Ir = In x Rating Plug Setting)
The rating plug varies the circuit breaker ampere rating as a function of its sensor size. Rating plugs
have nine dial settings; the multiplier values corresponding with each setting are printed on the rating
plug. The maximum setting range is 0.4–1.0 x In.

Enclosure Sizes
All ET electronic trip UL/IEC M-frame, P-frame and R-frame circuit breakers are available as standard
rated circuit breakers. Micrologic electronic trip UL/IEC circuit breakers are also available in 100%
rated constructions. Because the additional heat generated when applying circuit breakers at 100% of
continuous current rating, the use of specially designed enclosures and 90°C (194° F) rated wire sized
per the 75°C (167° F) NEC chart is required
Circuit breakers with 100% rating can also be used in applications requiring only 80% continuous loading.
Operating Conditions
Temperature
To meet the requirements of the UL489 Standard, molded case circuit breakers are designed, built and
calibrated for use on 50/60 Hz ac systems in a 40°C (104°F) ambient environment. Electronic trip
circuit breakers, however, are designed to react only to the magnitude of the current flowing through
the circuit breaker and are inherently ambient insensitive. Both UL/IEC and IEC-only circuit breakers
may be operated at temperatures between -25°C and +70°C (-13°F and 158°F). For temperatures
other than 40°C (104°F), the circuit breakers must be re-rated as shown.
Altitude
CIrcuit breakers are suitable for use at altitudes up to 13,100 ft. (4000 m). For altitudes higher than
6560 ft. (2000 m), circuit breakers must be derated as shown.

IEC 68-2-1—Dry cold at -55°C
IEC 68-2-2—Dry heat at +85°C
Damp heat (tropicalization)
IEC 68-2-30—Damp heat (temperature 55°C and relative humidity of 95%, condensing)
IEC 68-2-52 level 2—Salt mist
The materials used in the PowerPact circuit breakers will not support the growth of fungus and mold.
Vibration
PowerPact circuit breakers meet IEC 60068-2-6 Standards for vibration.
2 to 13.2 Hz and amplitude 0.039 in. (1 mm)
13.2 to 100 Hz constant acceleration
Storage Temperature
Circuit breakers with trip units without LCD displays may be stored in the original packaging at
temperatures between -58°F (-50°C) and 185°F (85°C). For circuit breakers with trip units with LCD
displays, this range is -40°F (-40°C) to 185°F (85°C).
Trip System
The trip system causes the circuit breaker to open automatically under overload, short-circuit or
equipment ground-fault conditions. Electronic trip circuit breakers give the customer more versatility to
achieve coordination with features such as adjustable instantaneous pickup and high withstand ratings.
The ET and Micrologic trip systems consist of current sensors, a microprocessor-based trip unit, and a
tripping coil. The tripping coil is a flux transfer solenoid that requires no external power source. All ET
and Micrologic protective functions are completely fault powered.
Micrologic Trip System
Features found in Micrologic® electronic trip circuit breakers, such as universally interchangeable
rating plugs, adjustable long-time pickups and 100% ratings also provide capacity for future growth.
The integral equipment ground-fault sensing capabilities available with Micrologic trip systems mean
that there are fewer parts and pieces to purchase, mount and wire. These capabilities include integral
ground-fault protection for equipment, which causes the circuit breaker to trip when a ground fault is
detected, as well as integral ground-fault alarm, which does not trip the circuit breaker but sends an
alarm when a ground fault is detected.
Certain Micrologic trip systems also offer the customer true power management system solutions through
communication. These trip units can communicate with other circuit breakers in the system and also with a
power monitoring system. Communication is by Modbus® and does not require proprietary software.
Communication between trip units allows zone-selective interlocking (ZSI) between circuit breakers at
different levels in the system. ZSI reduces fault stress by allowing the upstream circuit breaker closest to the
fault to ignore its preset delay time and trip without any intentional delay on a short circuit or ground fault.
For more information on ZSI, see data bulletin Reducing Fault Stress with Zone-Selective Interlocking.

Communication with a power monitoring system through a communications network allows a ground
fault to be reported without interrupting power to the system. It also allows the power monitoring
system to remotely report power usage, current flow, and trip history.
Instantaneous OFF Feature
Micrologic® 5.0 and 6.0 Standard, A, P and H electronic trip units provide the unique ability to turn the
instantaneous tripping function OFF. Turning off the instantaneous trip function increases the current
level at which the circuit breaker will trip with no intentional delay to the level of the short-time
withstand rating. This current level is typically much higher than any of the pickup levels provided by
the adjustable instantaneous feature. Therefore, using the instantaneous OFF feature improves
coordination by allowing the user to take advantage of the circuit breaker withstand rating.
Motor Circuit Protectors
An instantaneous trip version of the electronic trip circuit breaker is also available for motor circuit
protection. These motor circuit protectors comply with NEC requirements for providing short-circuit
protection when installed as part of a Listed combination controller having motor overload protection.
Electronic trip motor circuit protectors are similar in construction to ET electronic trip circuit
breakers.They are designed as disconnect devices for use in combination with motor starters. These
motor circuit protectors provide short-circuit protection only and have an adjustable amperage pickup
so they can be set to open instantaneously at current values slightly above the motor starting inrush
current. This setting coordinates the pickup time-current response of the motor circuit protector with
the overload relay of the motor starter to give the best possible protection.
Current interrupting ratings for these UL Recognized components are established in combination with
motor starters and properly-sized overload relays and contactors.
Automatic Molded Case Switches
P-frame, R-frame and NS630b–NS3200 circuit breakers are also available in automatic molded case
switch construction. Automatic switches are similar in construction to electronic trip circuit breakers,
except that the switches open instantaneously at a factory-set non-adjustable trip point calibrated to
protect only the molded case switch itself. Because of their molded case construction, they are more
compact than conventional disconnect switches and accept electrical accessories for added flexibility.
Molded case switches are intended for use as disconnect devices only. UL489 requires molded case
switches to be protected by a circuit breaker or fuse of equivalent rating. Molded case switches are
labeled with their appropriate withstand ratings. The withstand rating of a switch is defined as the
maximum current at rated voltage that the molded case switch will withstand without damage when
protected by a circuit breaker with an equal continuous current rating.
Table 8: P-, and R-Frame Withstand Ratings1

without damage when protected by a circuit breaker with an equal continuous current rating.

Internal Operating Mechanism
Manually-Operated Circuit Breakers
M-frame, P-frame, R-frame and NS630b–NS3200 manually-operated circuit breakers have a single
operating handle that acts directly through the operating mechanism against the contact blades. Multi-
pole circuit breakers have a common trip bar for positive action of all poles on manual and automatic
operation. These circuit breakers have a trip-free mechanism that allows them to trip even though the
operating handle may be restricted (by a handle operating mechanism or padlock attachment) in the
I/ON position. If not restricted, the operating handle moves to a position between I/ON and O/OFF
when the circuit breaker is tripped.
The face of the manually-operated circuit breakers is marked with standard ON/OFF and international
I/O markings to indicate handle position. In addition, the I/OFF portion of the circuit breaker handle is
color coded green.
Electrically-Operated Circuit Breakers
P-frame and NS630b–NS1600 circuit breakers are also available with a two-step stored-energy
mechanism which can be charged manually or using a motor. The closing time is less than five cycles.
Closing and opening operations can be initiated by remote control or by push buttons on the front cover.
An O-C-O (open-close-open) cycle is possible without recharging.
The face of electrically-operated circuit breakers is also marked ON/OFF and I/O, and equipped with a
position indicator to show contact position.
Push-to-Trip Button
The push-to-trip button located on the face of each manually-operated circuit breaker is a standard
feature on these circuit breakers. This allows the user to manually trip the circuit breaker without
risking exposure to live parts. During normal on-off operation, the handle opens and closes the circuit
breaker contact but does not exercise the tripping mechanism.
Use the push-to-trip button to:
Exercise the circuit breaker mechanism
Check the auxiliary and alarm switch circuits

Unit-Mount Circuit Breakers
Unit-mount M-frame, P-frame, R-frame and NS630b–NS3200 circuit breakers are individually-mounted
using supplied mounting screws. The four mounting screws are inserted through mounting holes
molded into the circuit breaker case and threaded into the circuit breaker mounting enclosure. To
properly support the circuit breaker, all four mounting screws must be used.
Unit-mount M-frame, P-frame and NS630b–NS1250 circuit breakers can be ordered with mechanical line
and load side lugs. The standard lugs can be removed for the installation of compression-type lugs or
bus connections. All lugs are UL Listed for their proper application and marked for use with aluminum
and copper (Al/Cu) or copper only (Cu) conductors. Lugs suitable for copper and aluminum conductors
are made of tin-plated aluminum. Lugs suitable for use with copper conductors only are made of copper.
See individual frame sections for frame-specific connection information.
I-Line® Circuit Breakers
M-frame circuit breakers through 800 A and P-frame and R-frame circuit breakers through 1200 A are
available in I-Line construction for easy installation and removal in I-Line panelboards and
switchboards. I-Line circuit breakers use “blow-on” type line side connectors. In case of a short circuit,
increased magnetic flux causes the plug-on connectors of the circuit breaker to tighten their grasp on
the panelboard or switchboard bus bars. The I-Line connectors and circuit breaker mounting bracket
are integral parts of I-Line circuit breakers and cannot be removed or replaced. I-Line circuit breakers
come with mechanical load side lugs.
Drawout Circuit Breakers
P-frame manually-operated circuit breakers and switches are also available in drawout construction.
The drawout assembly mechanism allows the circuit breaker to be racked in four positions (connected,
test, disconnect or withdrawn).
P-frame cradles are ordered separately and are available with factory and field-installed accessories.
See Section 9—P-Frame Cradles and Cradle Accessories for details.

Testing Requirements
UL, NEMA, CSA, and NMX requirements
The UL, NEMA, CSA and NMX labels on a circuit breaker indicate that the circuit breaker meets the
requirements of UL Standard 489, NEMA Standard AB-1, CSA Standard 22.2 No. 5-02 and NMX standard
J266. The labels also mean that the production procedure is monitored by UL, CSA and ANCE inspectors
to ensure continued compliance to these standards. These requirements include the following tests:
200% Overload Calibration—each pole of the circuit breaker must trip within a specified time limit
when carrying 200% of its continuous current rating.
135% Overload Calibration—with all poles connected in series, the circuit breaker must trip within a
specified time limit while carrying 135% of its continuous current rating.
Overload—the circuit breaker must make and break 600% of its continuous current rating at rated
voltage. Circuit breaker frame sizes 125–1600 A must perform 50 operations at 600%. Circuit
breaker frame sizes 2000–2500 A must perform 25 operations at 600%.
Temperature Rise—while carrying 100% of rated current and mounted in open air, temperature
rise on a wiring terminal must be within specified limits. For 100% rating, the circuit breaker is
mounted in an enclosure.
Endurance—UL489 requires that the circuit breaker must complete, at minimum, the following
number of operations:
Calibration—both the 200% and 135% overload calibration tests are repeated after endurance
testing.
Short Circuit—the circuit breaker shall be subjected to test currents based on voltage rating and
frame size, with the type and number of operations based on the number of poles, frame rating and
voltage rating. Example: a 3P, 600 Vac, 2500 A frame circuit breaker is subjected to one 20 kA
single-phase closing of the circuit on the circuit breaker per pole and one 30 kA three-phase closing
of the circuit on the circuit breaker for a total of seven short circuit tests.
Trip Out—the 200% thermal calibration test is repeated following the short-circuit tests.
Dielectric—the circuit breaker must withstand, for one minute, twice its rated voltage plus 1000 V:
Between line and load terminals with the circuit breaker in the open, tripped and OFF positions.
Between terminals of opposite polarity with the circuit breaker closed.
Between live parts and the overall enclosure with the circuit breaker both open and closed.
No conditioning of the circuit breaker can take place during or between tests. There can be no failure of
functional parts at the conclusion of the sequences.
After qualifying a set of circuit breakers to the standard tests, a manufacturer can have additional
circuit breaker samples tested on higher than standard available fault currents. The following
performance requirements apply:
200% Overload Calibration—each pole of the circuit breaker must trip within a specified time limit
when carrying 200% of its continuous current rating.
Short-circuit Test—with the load side terminals connected by 10-inch lengths of specified cable (or
a shorting bar), the circuit breaker is exposed to a short-circuit current for a set time interval. After
safe interruption, the circuit breaker is reset and closed again on the short circuit.

Section 2—Electronic Trip Systems
M-frame circuit breakers are available with the ET 1.0 electronic trip system. P-frame and R-frame
circuit breakers are available with either the ET1.0I basic electronic trip system or the Micrologic®
electronic trip system. The NS630b–NS3200 circuit breakers are available with the Micrologic
electronic trip system. The sensing system responds to the flow of current through the circuit breaker.
Thermal Imaging
The thermal imaging function protects the cables or bus bars from overheating in case of low
amplitude repetitive faults. Such overheating can be due to repetitive motor startings, fluctuating load,
intermittent ground faults, or subsequent closing after a fault. Traditional electronic protection does not
protect against repetitive faults because the duration of each overload above the pickup setting is too
short to achieve effective tripping. Nevertheless, each overload involves a temperature rise in the
installation, the cumulative effect of which could lead to overheating of the system.
The thermal imaging function remembers and integrates the thermal heating caused by each pickup
setting overrun. Before tripping, the integrated heating value will reduce the associated time delay and,
therefore, the reaction of the trip unit will be closer to the real heating of the power network system. After
tripping, the function will also reduce the time delay when closing the circuit breaker on an overload.
True RMS Current Sensing
The sensing system responds to the flow of current through the circuit breaker. The trip unit samples
the current waveform to provide true RMS protection through the fifteenth harmonic. This true RMS
sensing gives accurate values for the magnitude of a non-sinusoidal waveform. Therefore, the heating
effects of harmonically distorted waveforms are accurately evaluated.
The Micrologic H trip unit provides additional sampling of the waveforms to measure and provide
waveform capture of harmonic distortion to the thirty-first harmonic.
ET Trip System
ET trip units are available with M-frame, P-frame and R-frame UL/IEC circuit breakers. Circuit breakers
with ET trip units have a fixed ampere rating. The trip units are not field-interchangeable and will not
accept any communications or other trip unit accessories. The trip system uses a set of current
transformers (called CTs or sensors) to sense current, a trip unit to evaluate the current, and a tripping
solenoid to trip the circuit breaker.
ET1.0 (M-Frame only)
The ET1.0 trip system is available on M-frame circuit breakers and is equipped with fixed long-time and
adjustable instantaneous tripping functions only. The long-time pickup is fixed at 1.0 x sensor rating (In),
while the instantaneous pickup is adjustable (dial settings from 2–10 x In) with no intentional time delay.
ET1.0I (P-Frame and R-Frame only)
The ET1.0I trip system is available on both P-frame and R-frame circuit breakers and is equipped with fixed
long-time and adjustable instantaneous tripping functions only. The long-time pickup is fixed at 1.0 x sensor
rating (In), while the instantaneous pickup is adjustable (dial settings from 1.5–12 x In) with no intentional
time delay.
ET1.0M (P-Frame only)
The ET1.0M trip system is only available on P-frame motor circuit protectors and provides protection for
short circuit conditions only. The trip unit has a single adjustment for instantaneous pickup that, if

exceeded, will trip the circuit breaker with no intentional delay. Instantaneous trip dial settings are
2–16 x In for 600 A circuit breakers and 1.5–12 x In for 800–1200 A circuit breakers.
Micrologic® Electronic Trip Systems
The P-frame, R-frame and NS630b–NS3200 electronic trip circuit breakers can be equipped with the
optional Micrologic trip systems listed below:
Trip units are designed to protect power circuits and loads. Micrologic trip systems use a set of current
transformers (called CTs or sensors) to sense current, a trip unit to evaluate the current, and a tripping
solenoid to trip the circuit breaker. Adjustable rotary switches on the trip unit allow the user to set the
proper overcurrent or equipment ground-fault current protection required in the electrical system. If
current exceeds a set value for longer than its set time delay, the trip system opens the circuit breaker.
Alarms may be programmed for remote indications. Measurements of current, voltage, frequency,
power, and power quality optimize continuity of service and energy management.
Integration of protection functions in the Application Specific Integrated Circuit (ASIC) electronic
component used in all Micrologic trip units guarantees a high degree of reliability and immunity to
conducted or radiated disturbances. On Micrologic P and H trip units, advanced functions are
managed by an independent microprocessor.
Circuit breakers are shipped with the trip unit long-time pickup switch set at 1.0 and all other trip unit
adjustments set at their lowest settings. Actual settings required for a specific application must be
determined by a qualified consultant or plant engineer. A coordination study is recommended to
provide coordination between all circuit breakers in the distribution system.

Ammeter Measurements
Micrologic A trip units measure the true RMS value of currents. They provide
continuous current measurement from 0.2 to 20 x In with an accuracy of 1.5%
(including sensors). No auxiliary source is needed where I > 0.2 x In. The optional
external power supply (24 Vdc) makes it possible to display currents where I < 0.2
x In and to store values of the interrupted current.
A digital LCD screen continuously displays the most heavily loaded phase (Imax)
or displays the Ia, Ib, Ic, Ig, and (on 4P circuit breakers only) In stored current and
setting values by successively pressing the navigation button.
Communication Network
In conjunction with an optional communication network, the trip unit transmits the
following parameters:
• Setting values
• All ammeter measurements
• Tripping causes.

Micrologic® 5.0P and 6.0P Trip Units with Power Metering
Load Shedding and Reconnection Parameters
Load shedding and reconnection parameters can be set according to the power or the current flowing
through the circuit breaker. Load shedding is carried out by a remote computer via the communication
network or by an M6C programmable contact.
Micrologic P trip units provide power metering and extended protection in addition
to the adjustable protection functions of the Micrologic A trip unit.
Protection Settings
The adjustable protection functions of the 5.0P and 6.0P trip units are identical to
those of Micrologic A trip unit (overloads, short circuits, equipment ground-fault
protection; see page 27). These units also feature:
• Fine adjustment
Within the range below the rotary switch setting, fine adjustments of
pickups/delays in steps of 1 A/s (except for short-time and ground-fault) are
possible on the keypad or remotely by the communication network.
• Inverse definite minimum time lag (IDMTL) setting.
Coordination with fuse-type or medium-voltage protection systems is
optimized by adjusting the long-time delay curve around 6 x Ir axis. This setting
ensures better coordination with certain loads.
• Neutral protection
On three-pole circuit breakers, neutral protection may be set using the keypad or
remotely using the communication network to one of four positions: OFF, 1/2N
(1/2 x In), 1N (1 x In), or 1.6N (2 x In).
NOTE: Neutral protection is disabled if long-time curve is set to one of the
IDMTL protection settings.
• Configuring Alarms and Other Protection Functions
When the cover is closed, the keypad may no longer be used to change the
protection settings, but it still provides access to the displays for
measurements, histories, indicators, etc. Depending on the thresholds and
time delays set, the Micrologic P trip unit monitors current, voltage, power,
frequency, and phase sequence. Each threshold overrun may be signalled
remotely via the communication network.
Each threshold overrun may be combined with tripping (protection) or an
indication carried out by an optional M6C programmable contact (alarm), or both
(protection and alarm).
Maintenance Record
The maintenance record can be consulted using the full-function test kit or
remotely via the communication network. It can be used as an aid in
troubleshooting and to assist scheduling for device maintenance operations.
Recorded indications include:
• Highest current measured
• Operation counter (cumulative total and total since last reset)
• Number of test kit connections
• Number of trips in operating mode

Real-Time Metering
The value displayed on the screen is refreshed every second. Minimum and maximum measurement
values are stored in memory.
Demand Metering
The demand is calculated over a fixed or sliding time window that can be programmed from five to sixty
minutes. Depending on the contract signed with the power supplier, specific programming makes it
possible to avoid or minimize the cost of overrunning the subscribed power. Maximum demand values
are systematically stored and time stamped.
Communication Network
The communication network may be used to:
Remotely read parameters for the protection functions.
Transmit all the measurements and calculated values.
Signal the causes of tripping and alarms.
Consult the history files and the maintenance indicator record.
In addition, an event log of the last 100 events and a maintenance record, which is stored in the trip
unit memory but not available locally, may be accessed via the communication network.
This Modbus® communication system is compatible with the Powerlogic® System ManagerTM software
(SMS).
Event Log
The event log may be accessed by a remote computer via the communication network. All events are
time stamped and include:
Trips
Beginning and end of alarms
Modifications to settings and parameters
Loss of time
Test kit connections
Counter resets
System faults (thermal self-protection, major fault and minor fault alarms)

Micrologic® 5.0H and 6.0H Trip Units with Harmonic Metering
Demand Metering: Similar to the Micrologic P trip unit, demand values are calculated over a fixed
or sliding time window that can be set from five to sixty minutes.
Waveform Capture
The Micrologic H trip units can capture and store current and voltage waveforms using digital sampling
techniques similar to those used in oscilloscopes. Using the information available in the captured
waveform, it is possible to determine the level of harmonics as well as the direction and amplitude of
the flow of harmonic power.
The Micrologic® H trip unit can record manually via the keypad the following waveforms:
Currents Ia, Ib, Ic and In
Phase-to-phase voltages Vab, Vbc, and Vca
In addition to the P functions, the Micrologic H trip units offer:
In-depth analysis of power quality including calculation of harmonics and the fundamentals
Diagnostics aid and event analysis through waveform capture
Customized alarm programming to analyze and track down a disturbance on the ac
power system
Systematic time stamping of all events and creation of logs
Metering
The Micrologic H trip unit offers all the measurements carried out by the Micrologic P trip unit, with
the addition of phase-by-phase measurements of power and energy as well as calculation of:
Current and voltage total harmonic distortion (THD, thd)
Current, voltage and power fundamentals (50/60 Hz)
Harmonic components (amplitude and phase) up to the 31st current and voltage
harmonic
Real-time metering: The value displayed on the screen is refreshed every second. The

Waveforms may be displayed on the graphic screen of the control unit or communicated over a
networked system. The recording takes place over one cycle with a measurement range of 1 to 1.5 In
for current and 0 to 690 volts for voltage. Resolution is 64 points per cycle.
Customized Alarm Programming
The instantaneous value of each measurement can be compared to user-set high and low thresholds.
Overrun of a threshold generates an alarm. Programmable action can be linked to each alarm, including
circuit breaker opening, activation of an M6C contact, recording of measurements in a log, etc.
Event Logs
Each event is recorded with:
The date, time, and name of the event
The event characteristics
Micrologic H trip units are designed to be used with an external 24 Vdc power supply.Current-based
protection functions require no auxiliary power source.
Additional Characteristics for Type P and H Trip Units
Setting the display language: System messages can be displayed in six different languages
(English - US, English - UK, French, German, Spanish, and Italian). The desired language is
selected via the keypad.
Protection functions: All current-based protection functions require no auxiliary source. Voltage-
based protection functions are connected to ac power via a voltage measurement input built into
the circuit breaker on the bottom side. (Optional external voltage measurement is available as a
factory-installed option.)
Accuracy of measurements (including sensors):
Voltage (V) 1%
Current (A) 1.5% (higher accuracy [1%] may be achieved with special calibration on the current
transformer [CT characterization option])
Frequency (Hz) 0.1 Hz
Power (W) and energy (Wh) 2.5%
The Micrologic H trip unit uses a dedicated metering data chain separate from the protection
data chain so that a greater number of data samples can be used for metering. This increases
the number of samples taken per time period, which in turn gives the H trip unit a higher degree
of metering accuracy.

Stored information: The fine setting adjustments, the last 100 events and the maintenance record
remain in the trip unit memory even when power is lost.
Reset: An individual reset, via the keypad or remotely, will reset alarms, minimum and maximum
data, peak values, counters and indicators.
Micrologic® Trip Unit Functions
Long-time Trip Functions
The long-time pickup switch sets the maximum current level the circuit breaker will
carry continuously. The maximum current level (Ir) is the long-time pickup setting
multiplied by the sensor plug amperage (In). If the current exceeds this value for longer
than the long-time delay time, the circuit breaker will trip.
The long-time delay switch sets the length of time that the circuit breaker will carry a
sustained overload before tripping. Delay bands are labeled in seconds of overcurrent
at six times the ampere rating. For maximum coordination, there are eight delay bands.
Long-time delay is an “inverse time” characteristic in that the delay time decreases as
the current increases.
The trip unit includes an alarm indicator that will be lit continuously when the current is
above 100% of the pickup setting.
Short-time Trip Functions
The short-time pickup switch sets the short-circuit current level at which the circuit
breaker will trip after the set short-time delay. The short-time current (Isd) equals the
short-time pickup setting multiplied by the long-time pickup (Ir).
The short-time delay switch sets the length of time the circuit breaker will carry a short
circuit within the short-time pickup range. The delay (based on 10 times the ampere
rating Ir) can be adjusted to four positions of I2t ramp operation (I2t ON) or five
positions of fixed time delays (I2t OFF). I2t ON delay is an “inverse time” characteristic
in that the delay time decreases as the current increases. Short-time delay for the 2.0
trip unit is fixed at a delay band of 20 to 80 ms.
Instantaneous Trip Function
The instantaneous pickup switch sets the short-circuit current level at which the circuit
breaker will trip with no intentional time delay. The instantaneous current (Ii) is equal to
the instantaneous pickup setting multiplied by the sensor plug amperage (In).
The instantaneous function will override the short-time function if the instantaneous
pickup is adjusted at the same or lower setting than the short-time pickup. In trip units
with both adjustable short-time and instantaneous trip functions, the adjustable
instantaneous trip can be disabled by setting Instantaneous pickup to OFF.

08/2009
Ground-fault Trip Functions
The ground-fault pickup switch sets the current level at which the circuit breaker will trip
after the set ground-fault delay. Ground-fault pickup values (Ig) are based on circuit
breaker sensor plug (In) only, not on the rating plug multiplier (Ir). Changing the rating
plug multiplier has no effect on ground-fault pickup values.
The ground-fault delay switch sets the length of time the circuit breaker will carry
ground-fault current which exceeds the ground-fault pickup level before tripping. The
delay, based on the sensor plug amperage (In), can be adjusted to four positions of I2t
ramp operation (I2t ON) or five positions of fixed time delays (I2t OFF). I2t ON delay is
an “inverse time” characteristic in that the delay time decreases as the current
increases.
Communication Network
P-frame, R-frame and NS630b–NS3200 circuit breakers and Micrologic® trip unit information is
available via a Modbus® communication network to Powerlogic® System ManagerTM software (SMS) or
third party applications for reporting and recording.
Types of Information via Modbus communication network includes:
Circuit breaker identification and status
Remote control of circuit breaker operation
View and set protection function parameters
Real-time readings
Trip indication
Alarm reporting
Historical files and maintenance records
The Modbus circuit breaker communication feature, standard on the Micrologic P and H trip units and
available for the Micrologic A trip unit, is made up of:
A Modbus Circuit Breaker Communication Module (BCM) installed on the circuit breaker and
supplied with a kit for optional connection to the XF shunt close and MX shunt trip
An optional Modbus Cradle Communication Module (CCM) installed adjacent to the circuit breaker
cradle. A set of cradle position switches is required for status of circuit breaker position (connected,
test, or disconnected). (Drawout circuit breaker only.)
Modbus Circuit Breaker Communication Module (BCM)
The Modbus Circuit Breaker Communication Module (BCM) is installed in the circuit breaker and
requires a separate, isolated 24 Vdc power source. The BCM is optically coupled to the Micrologic trip
unit to ensure a high level of isolation between the trip unit and the communication network. The
Modbus BCM provides circuit breaker status via dedicated OF (open or closed) and SDE (fault tripped)
switches and provides the capability of remotely controlling the circuit breaker. It also maintains an
event log of circuit breaker status containing the number of times the circuit breaker has experienced
each status position with the date and time of the last transition. This information and the remote
control capability are available to a Modbus supervisor system via a Modbus communication network.

Modbus Cradle Communication Module (CCM)
The optional Modbus Cradle Communication Module (CCM) (drawout circuit breakers only) is installed
adjacent to the circuit breaker cradle and is the gateway between the Modbus network and the Modbus
BCM. The Modbus CCM provides circuit breaker cradle status including connected position (CE),
disconnected position (CD) and cradle test position (CT). The CCM monitors the position of the
Modbus BCM and trip unit when it detects a circuit breaker being racked from the disconnected to the
test position. This capability allows a circuit breaker to be replaced without the need to manually
configure the communication parameters in the Modbus BCM. The CCM maintains an event log of the
date and time of the last circuit breaker transition. In order to aid system communication troubleshooting,
the CCM has visual indication of the module’s operating status by means of two LEDs.
Powerlogic® System Manager Software (SMS)
System Manager Software (SMS), used for power systems and energy management, provides the
human-machine interface (HMI) for electrical system information on a PC. SMS displays circuit breaker
and trip unit information in several formats including:
Graphical screens including real-time readings, circuit breaker status and remote control of circuit
breaker operation
Tables displaying real-time readings, maintenance information and date and time of last operation
Waveform captures including harmonic content
Tabular displays of event logs and data logs
Alarm annunciation and recording

Continuous Current Rating
All circuit breakers marked as 100% rated can be continuously loaded to 100% of their rating.
Because of additional heat generated when applying circuit breakers at 100% of continuous current rating,
the use of specially-designed enclosures and 90°C (194°F) wire is required. The 90°C (194°F) wire must be
sized according to the ampacity of the 75°C (167°F) wire column in the NEC. Minimum enclosure size and
ventilation specifications are indicated on the circuit breaker and in it’s instruction bulletin and in Table 5 on
page 11.
Circuit breakers with 100% rating can also be used in applications requiring only 80% continuous loading.

Automatic Molded Case Switches1
Automatic molded case switches are available in individually-mounted and I-Line constructions from
600–1200 A. Automatic switches are similar in construction to electronic trip circuit breakers except
that long-time tripping is not present. The switches open instantaneously at a non-adjustable magnetic
trip point calibrated to protect only the molded case switch itself. They must be used in conjunction with
a circuit breaker or fuse of equivalent rating.
1Catalog numbers for automatic switches are designated by “000” in positions 7–9 (ampere rating) and S60, S80, S10, or S12 in
positions 11–14 (trip system). See Table 10.

Motor Circuit Protectors1
Motor circuit protectors are similar in construction to thermal-magnetic circuit breakers, but have only
instantaneous trip functions provided by the ET1.0M trip unit. These motor circuit protectors comply
with NEC requirements for providing short-circuit protection when installed as part of a listed
combination controller having motor overload protection. Interrupting ratings are determined by testing
the motor circuit protector in combination with a contactor and overload relay.
Motor circuit protectors are available in PJ and PL individually-mounted and I-Line® construction.
According to the NEC, the instantaneous trip of the motor circuit protector may be set to a maximum of
8 to 17 times motor Full Load Amps (FLA), but a setting as close as possible to inrush current (without
nuisance tripping) results in the best protection. The instantaneous trip pickup level is adjustable within
the ranges shown below.
NOTE: Continuous currents larger than the ampere rating can damage the motor circuit protector.
Select motor circuit protectors as follows:
1. Determine motor horsepower (hp) rating from the motor nameplate. The selection table is suitable
for motors with locked-rotor indicating code letters per NEC Table 430-7 (b) as follows:
For other motors contact the field office.
2. Select a motor circuit protector with an ampere rating recommended for the hp and voltage
involved.
3. Select an adjustable trip setting of at least 800% but not to exceed 1300% (1700% for high-
efficiency motors) of the motor full load amperes (FLA).
4. The NEC 1300% maximum setting (1700% for high-efficiency motors) may be inadequate for
motor circuit protectors to withstand current surges typical of the magnetization current of auto-
transformer type reduced voltage starters or open transition wye-delta starters during transfer from
“start” to “run,” constant hp multi-speed motors and motors labeled “high efficiency.”
5. Part-winding motors, per NEC 430-3, should have two motor circuit protectors selected from the
above at not more than one-half the allowable trip setting for the horsepower rating. The two circuit
protectors should operate simultaneously as a disconnecting means per NEC 430-103.
1Catalog numbers for motor circuit protectors are designated by M68, M69, or M70 in positions 11–14 (trip system). See Table 10.

Electrically-Operated Circuit Breakers
Electrically-operated P-frame circuit breakers are available in I-Line® and unit-mount construction up
to 1200 A and are denoted in the catalog number by an “M_” suffix. These come equipped with a two-
step stored energy mechanism and come standard with a motor assembly. These are available
factory-installed only.
Motor assemblies provide on and off control from remote locations. The assemblies contain a spring-
charging motor (MCH), a shunt trip (MX) and a shunt close (XF) and are available in standard or
communicating versions. When remote indication of the circuit breaker status is required, use of a
circuit breaker with an OF auxiliary switch for on-off indication or with an SDE overcurrent trip switch
for trip indication is necessary. See Table 68 on page 70 for details.
Termination Information
Unit-mount circuit breakers and switches have mechanical lugs standard on both ends. I-Line circuit
breakers have lugs standard on the O/OFF end. These lugs accept aluminum or copper wire.
Manually-operated P-frame circuit breakers are also available in drawout construction. See Table 82
on page 79 for more lug options.
Control Wiring
Control wiring for unit-mount and I-Line construction is connected to terminals located under the circuit
breaker accessory cover. Control wiring for drawout construction is connected to terminals located on
the cradle.

Section 5—PowerPact® R-Frame Circuit Breakers
Performance
Providing unparalleled performance and control, the P-frame circuit breakers features the exclusive
Micrologic® electronic trip units, which allow for a range of sophisticated applications for metering and
monitoring. In addition, trip units can be interchanged in the field to allow for maximum flexibility.
The compact size and smaller footprint of the R-frame circuit breaker permits higher density
installations using I-Line® panelboards and switchboards. These circuit breakers are available in 100%
rated construction up to 3000 A to meet a broad range of commercial and industrial application needs.
Both standard and 100% rated construction circuit breakers are available in 3000 A with a sensor
size range of 600–3000 A.
Interrupting ratings (AIR):
G: 35 kAIR at 480 Vac
J: 65 kAIR at 480 Vac
K: 65 kAIR at 480 Vac
L: 100 kAIR at 480 Vac
The K interrupting rating is recommended for applications having high inrush and/or non-linear
loads such as large motors, transformers, motors with soft starts, etc.
Compact circuit breaker size allows for smaller footprint installations using I-Line panelboards and
switchboards. Fifteen-inch width provides increased density installation.
Most field-installable accessories are common to all frame sizes for easier stocking and installation
Selection of four interchangeable Micrologic trip units available, with Powerlogic® power metering
and monitoring capabilities available in advanced trip units.
Compatible with Powerlogic systems and high amperage power circuit breakers.
Built-in Modbus® protocol provides an open communications platform and eliminates the need to
purchase additional, proprietary network solutions.
Connection options include bus, cable or I-Line for installation flexibility.
Additional options are available for 5-cycle closing and stored energy mechanisms.

Interrupting Ratings
Automatic Molded Case Switches
Automatic molded case switches are available in unit-mount construction from 1200–2500 A.
Automatic switches are similar in construction to electronic trip circuit breakers except that long-time
protection is not present. The switches open instantaneously at a non-adjustable magnetic trip point
calibrated to protect only the molded case switch itself. They must be used in conjunction with a circuit
breaker or fuse of equivalent rating.
NOTE: Catalog numbers for automatic switches are designated by “000” in positions 7–9 (ampere
rating) and S60, S80, S10, or S12 in positions 11–14 (trip system). See Table 10..

Termination Information
I-Line® circuit breakers have lugs standard on the O/OFF end. Unit-mount circuit breakers and
switches are equipped for direct bus connection. For certain circuit breaker ratings and to connect
cable to R-frame circuit breakers, an RLTB terminal pad kit may be required. Refer to Section
10—Dimensional Drawings for terminal pad kit dimensions.
For cable connection to RLTB, use AL2500RK lug. See page 79.
Continuous Current Rating
All circuit breakers marked as 100% rated can be continuously loaded to 100% of their rating.
100%-rated circuit breakers are available in unit-mount construction up to 3000 A and in I-Line
construction up to 1200 A.
Because of the additional heat generated when applying circuit breakers at 100% of continuous
current rating, the use of specially-designed enclosures and 90°C (194°F) wire is required. The 90°C
(194°F) wire must be sized according to the ampacity of the 75°C (167°F) wire column in the NEC.
Minimum enclosure size and ventilation specifications are indicated on a label on the circuit breaker, in
the circuit breaker instruction bulletin and in Table 5 on page 11.
Circuit breakers with 100% rating can also be used in applications requiring only 80% continuous
loading.
Control Wiring
Control wiring is connected to terminals located under the circuit breaker accessory cover.

Electrically-Operated Circuit Breakers
Electrically-operated NS630b–NS1600 circuit breakers are available in unit-mount construction up to
1600 A and are denoted in the catalog number by an “M_” suffix. These come equipped with a two-
step stored energy mechanism and come standard with a motor assembly.
Motor assemblies provide on and off control from remote locations. The assemblies contain a spring-
charging motor (MCH), a shunt trip (MX) and a shunt close (XF) and are available in standard or
communicating versions. When remote indication of the circuit breaker status is required, use of a
circuit breaker with an OF auxiliary switch (for on-off indication) or with an SDE overcurrent trip switch
(for trip indication) is necessary.
For catalog numbers, see Table 68 on page 70.
Automatic Molded Case Switches
Automatic molded case switches are available in unit-mount constructions from 630–1600 A.
Automatic switches are similar in construction to electronic trip circuit breakers except that long-time
protection is not present. The switches open instantaneously at a non-adjustable magnetic trip point
calibrated to protect only the molded case switch itself. They must be used in conjunction with a circuit
breaker or fuse of equivalent rating.
Termination Information
Unit-mount circuit breakers and switches have mechanical lugs standard on both ends. These lugs
accept aluminum or copper wire. Circuit breakers are also available in drawout construction.
Other terminations are available as accessories for non-standard applications. See Table 82 on page
79 for more lug options.
Accessories
Accessories are available either factory-installed or field-installable. They can be installed in accessory
compartments behind the circuit breaker accessory cover. See Table 60 on page 66 for available
accessories.
Control Wiring
Control wiring is connected to terminals located under the circuit breaker accessory cover.

Shunt Trip (MX)
The shunt trip provides a means of tripping the circuit breaker electrically from a remote location using
an external voltage source. The shunt trip may be supplied continuously or intermittently.
Communication versions of the shunt trip are available for direct connection via the circuit breaker
communication module (BCM).
The inrush currents for these devices are approximately 200 VA. When low supply voltages (12, 24 or
48 Vdc) are used, the maximum allowable wire length is dependent on the voltage and the wire size.

Undervoltage Trip (MN)
The undervoltage trip accessory trips the circuit breaker when the voltage drops to a value between
35% and 70% of the control voltage. If the undervoltage trip is not energized, it is impossible to close
the circuit breaker, either manually or electrically. An attempt to close the circuit breaker produces no
movement of the main contacts. Closing is allowed when the supply voltage of the undervoltage trip
reaches 85% of the rated voltage.
The inrush currents for these devices are approximately 200 VA. When low supply voltages (12, 24 or
48 V) are used, the maximum allowable wire length is dependent on the voltage and the wire size.
Time-Delay Module for Undervoltage Trip
To eliminate circuit breaker nuisance tripping during temporary voltage dips (micro-breaks), operation
of the undervoltage trip (MN) can be delayed by adding an external time-delay module to the
undervoltage trip circuit. Available as adjustable and non-adjustable module.

Switches
Auxiliary Switch (OF)
An auxiliary switch is a single-pole double-throw switch operated by the movable contact arm assembly.
It is used to remotely indicate the position of the main circuit breaker contacts, whether open or closed.
Auxiliary switches can be used to operate indicator lights, relays or other accessories. An R-frame,
P-frame or NS630b–NS3200 circuit breaker can accommodate up to three 1A/1B auxiliary switches. The
auxiliary switch is also available in a low-level version capable of switching very low loads
Alarm Switch (SD)
The alarm switch indicates that the circuit breaker has tripped due to an overload, short circuit,
operation of a voltage release, operation of the push-to-trip button or disconnection when the device is
on. The alarm switch returns to the de-energized state when the circuit breaker is reset. The alarm
switch is also available in a low-level version capable of switching very low loads.
Overcurrent Trip Switch (SDE)
The overcurrent trip switch indicates that the circuit breaker has tripped due to an overload, ground
fault or short circuit and returns to the de-energized state when the circuit breaker is reset. This switch
is also available in a low-level version capable of switching very low loads.

Lead-Free Trip Unit Sealing Kit
The MICROTUSEAL lead-free trip unit seal was designed as a RoHS-compliant replacement for lead
seals. It may be used to seal Micrologic trip units and other devices. It is manufactured as a stainless
steel cable and polycarbonte locking mechanism which shows evidence of tampering. The seal is
individually numbered for control purposes.

Neutral Current Transformer (CT)
Current transformers are available for applications requiring ground-fault protection on three-phase,
four-wire systems or for neutral protection and metering. Neutral current transformers are not required
on non-ground-fault circuit breakers, or on three-phase, three-wire systems. The rating of the external
neutral current transformer must be compatible with the rating of the circuit breaker.
NOTE: These neutral current transformers cannot be used for SGR (Source Ground-Return) or MDGF
(Modified Differential Ground Fault) applications.
Ground-Fault Interface Module
The ground-fault interface module (R-frame and NS1600b–NS3200 circuit breakers only) is used to
sum the current flow in three-phase, four-wire systems and multiple-sourced systems, using one or
more specially-designed external current sensors to measure current flow. The ground-fault interface
module is commonly used in two applications:
For a ground-source return ground-fault sensing system
For a modified differential ground-fault (MDGF) system
More complex systems are possible, for information about these, contact a field sales representative.

External Sensor for SGR or MDGF Protections
For use on 400 A sensor or higher.
In SGR applications, an external sensor is installed around the connection of the transformer neutral
point to ground. Its secondary is connected to the Micrologic® 6.0A, 6.0P or 6.0H trip units.
In MDGF applications, a sensor is installed on each phase and neutral conductor. The sensors for
each circuit breaker are connected to an interface module. These, in turn, connect to the Micrologic
6.0A, 6.0P or 6.0H trip units.

Sensor Plugs
Sensor plugs are used to set the current rating (In) of the PowerPact® P- and R-frame circuit breakers.
Beginning in January 2007 (date code 07011), the sensor plugs are field-replaceable, down to 50% of
the original rating. Mechanical keying in the circuit breaker prevents changing a rating plug to a higher
rating than the original factory-installed sensor plug.

Rating Plugs
Interchangeable rating plugs are available to limit the long-time threshold setting range for greater
versatility.
M2C and M6C Programmable Contacts
The M2C and M6C contacts are used with the Micrologic® P and H control units, and indicate the type
of fault and instantaneous or delayed threshold overruns (i.e: trip unit protection pickup,
current/voltage unbalance, under/over voltage, reverse power, phase rotation, under/over frequency,
and load shedding). The M2C has two programmable contacts while the M6C has six. They require an
external 24 Vdc power supply (100 mA consumption).
NOTE: The M2C and M6C may use the same 24 V power supply as the trip unit. The M2C, M6C and
trip unit power supply must be separate and isolated from the power supply used for the BCM/CCM.
M6C contacts are programmed via the control unit using a keypad or via a supervisory station with the
COM communication option. They may be programmed:
With instantaneous return to the initial state
Without return to the initial state
With return to the initial state following a delay

Zone-Selective Interlocking (ZSI)
Restraint Interface Module (RIM)
The restraint interface module (RIM) is used to allow zone-selective interlocking communications
between circuit breakers with old Micrologic®, Merlin Gerin®, or Federal Pioneer® trip units and GC
series ground-fault relays. For 120 Vac/24 Vdc systems, use catalog number S48890. For 240 Vac/24
Vdc systems, use catalog number S48895.
Downstream circuit breakers with Micrologic 2.0A, 5.0A, 5.0P, 5.0H, 6.0A, 6.0P, and 6.0H trip units can
restrain up to fifteen upstream circuit breakers with Micrologic 5.0A, 5.0P, 5.0H, 6.0A, 6.0P, and 6.0H
trip units without requiring a restraint interface module. If the number of upstream circuit breakers
exceeds fifteen, then a RIM is required.
ZSI is used to reduce the stress on electrical distribution equipment during fault
conditions by reducing the time it takes to clear the fault, while maintaining
system coordination between overcurrent protective devices.
During a short-circuit or ground-fault condition on a ZSI system, the device
directly ahead of the fault sends a signal upstream via control wiring to restrain
upstream circuit breakers from tripping and then trips with no intentional time
delay to clear the fault. Upstream devices which receive a restraint signal obey
their short-time and/or ground-fault delay settings to maintain coordination in
other areas of the system. Upstream devices that do not receive a restraint
signal trip with no intentional time delay.
Fault 1—The upstream circuit breaker (A) will clear the fault with no
intentional delay, regardless of its time-delay setting.
Fault 2—Circuit breaker (B) will inform upstream circuit breaker (A) that it is
clearing the fault. This will prevent circuit breaker (A) from tripping
instantaneously. Circuit breaker (A) will trip at the end of its time delay setting
if the fault is not cleared during this time.
ZSI requires trip settings be coordinated so a downstream circuit breaker will trip
before an upstream circuit breaker under overload, short-circuit or ground-fault
conditions. Effective coordination requires a system coordination study. See data
bulletin 0100DB0501, Short Circuit Coordination for Low-Voltage Circuit Breakers.

Circuit Breaker Terminations
Mechanical, Compression, and Distribution Lugs
The M-frame, P-frame and NS630b–NS1250 circuit breakers have mechanical lugs standard on both ends
of the unit-mounted circuit breakers. The M-frame and P-frame I-Line® circuit breakers have mechanical
lugs standard on the O/OFF end only. These lugs are suitable for use with copper or aluminum wire. Rear
connectors, compression lugs and distribution lugs are available for special applications.
P-frame and NS630b–NS1600 circuit breakers are also available in drawout construction. See
Section 8 for drawout cradle details.
The R-frame and NS1600b–NS3200 circuit breakers have terminal pads only (no lugs) for bus
connections on both ends. Terminal pads are required for the use of lugs on R-frame circuit breakers,
lugs are not available for NS1600b–NS3200 circuit breakers. See the section on R-frame and
NS1600b–NS3200 circuit breakers for information on terminal pad requirements.
Copper mechanical lugs are available for use with copper wire only. These lugs can be factory
installed by adding an LC suffix to the circuit breaker catalog number for standard copper lugs and LD
suffix for high-amp copper lugs (M-frame, P-frame and NS630b–NS1250 d800 A circuit breakers
only). See the Digest or product selector or contact the field office for more information.
I-Line® Jaw Configurations
Standard 3P I-Line circuit breakers are supplied with an ABC phase jaw connection. In applications
where the jaw configuration must be reversed, specify a CBA jaw configuration by adding the digit 6 to
the phasing position of the circuit breaker catalog number.
I-Line 2P circuit breakers are available in AC or CA phasing. Add the digit of the desired phasing to the
phasing position of the circuit breaker catalog number.
