PowerPact™ H-, J-, and L-Frame Circuit Breakers
General Information
10
07/2014
Section 2—General Information
The PowerPact™ H-, J-, and L-frame circuit breakers are designed to protect electrical systems from
damage caused by overloads and short circuits. H- and J-frame circuit breakers are available with
either thermal-magnetic or Micrologic™
electronic trip units. L-frame circuit breakers are available with
Micrologic electronic trip unit.
H- and J-frame circuit breakers with thermal-magnetic trip units contain individual thermal (overload)
and instantaneous (short circuit) sensing elements in each pole. The amperage ratings of the thermal
trip elements are calibrated at 104°F (40°C) free air ambient temperature. Per the National Electric
Code
®
(NEC
®
) and the Canadian Electrical Code, standard circuit breakers may only be applied
continuously at up to 80% of their rating. Circuit breakers rated for 100% operation are available but
require specially-designed enclosures, copper lugs, and 194°F (90°C) rated wire.
Devices with the Micrologic electronic trip unit provide adjustable protection settings for greater system
flexibility. In addition to electronic protection, Micrologic trip units allow users to monitor both energy
and power. Through direct access to in-depth information and networking using open protocols,
PowerPact circuit breakers with Micrologic trip units let operators optimize the management of their
electrical installations. Far more than a circuit breaker, these circuit breakers are a measurement and
communication tool ready to meet energy-efficiency needs through optimized power requirements,
increased energy availability, and improved installation management.
Applications
PowerPact H-, J-, and L-frame circuit breakers offer high performance and a wide range of
interchangeable trip units to protect most applications.
Electronic trip units provide highly accurate protection with wide setting ranges and can integrate
measurement, metering and communication functions. They can be combined with the front display
module (FDM121) to provide functions similar to a power meter.
Table 3: Applications
Power Meter
PowerPact H-, J-, and L-frame circuit breakers equipped with Micrologic 5 / 6 trip units offer
type A (ammeter) or E (energy) metering functions as well as communication capability. Using
Micrologic trip unit sensors and intelligence, PowerPact H-, J-, and L-frame circuit breakers
provide access to measurements of all the main electrical parameters on the built-in screen, on a
dedicated front display module (FDM121) or through the communication network.
Operating assistance
Integration of measurement functions provides operators with operating assistance functions
including alarms tripped by user-selected measurement values, time-stamped event tables and
histories, and maintenance indicators.
Front display module
The main measurements can be read on the built-in screen of Micrologic 5 / 6 trip units. They
can also be displayed on the equipment FDM121 along with pop-up windows signalling the main
alarms.
Communication Network
PowerPact H-, J-, and L-frame circuit breakers equipped with Micrologic 5 / 6 trip units provide
communication capabilities. Simple RJ45 cables connect to a Modbus communication interface
module.

Protection of distribution
systems
Mission critical applications
The PowerPact H-, J-, and L-frame circuit breakers provide protection against short circuits and
overloads for:
distribution systems supplied by transformers
distribution systems supplied by engine generator sets
They are easily installed at all levels in distribution systems, from the main LV switchboard to the
subdistribution boards and enclosures. All PowerPact circuit breakers can protect against
insulation faults by adding an external Vigirex relay.
The PowerPact H-, J-, and L-frame mission critical circuit breakers provide high levels of
selective coordination with QO and ED/EG/EJ circuit breakers.
Protection of motors
The PowerPact H-, J-, and L-frame circuit breakers include a number of versions to protect
motor applications:
basic short-circuit protection with electronic instantaneous only MCP or the electronic
Micrologic 1.3 M trip units, combined with a special overload relay to provide thermal
protection
protection against overloads, short circuit and phase unbalance or loss with Micrologic 2 M
trip units
The exceptional limiting capacity of the PowerPact circuit breakers automatically provides
coordination with the motor starter.
Protection of special
applications
The PowerPact H-, J-, and L-frame circuit breakers offer a number of version for special
protection applications:
industrial control panels with:
— compliance with international standards IEC 60947-2 and UL 508/CSA 22.2 N°14
—compliance with UL 489
— installation in universal and functional enclosures
400 Hz systems
Control using automatic
switches
An automatic switch version of PowerPact H-, J-, and L-frame circuit breakers is available for
circuit control. All add-on functions for the circuit breakers may be combined with the basic
automatic switch function, including motor operators.
For information on other automatic switches, contact Schneider Electric.
Manual transfer systems
To ensure a continuous supply of power, some electrical installations are connected to two
power systems:
the normal source, usually the utility (U)
a replacement source to supply the installation when the normal source is not available,
generally from a generator (G)
A mechanical and/or electrical interlocking system between two circuit breakers or automatic
switches avoids all risk of parallel connection of the sources during switching.
A system can be manual transfer mechanical device interlocking.

PowerPact™ H-, J-, and L-Frame Circuit Breakers
General Information

Mission Critical Circuit Breakers
The PowerPact
J- and L-Frame Mission Critical circuit breakers deliver high levels of selective
coordination in a flexible design that can be easily configured for a variety of applications. Tested to be
selectively coordinated with the QO
family of miniature circuit breakers and the ED, EG, and EJ
circuit breakers, this solution provides peace of mind when power availability is critical.
An electronic trip unit provides adjustable long-time settings in three sensor sizes, allowing coverage
from 70 through 600 A on 120-240, 208Y/120, 240, and 480Y/277 V systems.
In addition to unique design attributes, the PowerPact Mission Critical circuit breakers have also
undergone rigorous testing procedures to certify the coordination with downstream circuit breakers—
combining innovative engineering with validated test results.
Apply Schneider Electric Mission Critical circuit breakers in emergency power distribution systems,
data centers, hospitals, or anywhere continuity of service is desired.
Theory of Operation
There are several dynamic forces between the PowerPact Mission Critical circuit breakers and
downstream circuit breakers when a fault occurs downstream of the branch circuit breaker. Many of
these events cannot be shown on the trip curve.
The PowerPact Mission Critical circuit breakers analyze the fault current to make decisions which
maximize selectivity with downstream circuit breakers. The trip units deploy a special selectivity delay
to allow downstream circuit breakers to clear. However, on very high faults or if the downstream circuit
breaker does not trip, the circuit breaker trips the mechanism instantaneously.
The combination of the PowerPact Mission Critical circuit breaker and downstream circuit breakers
shown in the selectivity charts in the instruction bulletin are selective due to the fact that the series
impedance and the let-through from the downstream circuit breaker does not produce enough energy
to trip the PowerPact Mission Circuit circuit breaker.
This system maximizes the interaction of the circuit breakers in series to allow selectivity.
Trip Units and Trip Curves
The PowerPact J- and L-Frame Mission Critical circuit breakers deliver high levels of selective
coordination with the QO™ family of miniature circuit breakers and the ED, EG, and EJ circuit breakers
in a flexible design that can be easily configured for a variety of applications. These circuit breaker can
be equipped with 3.2-W, 3.2S-W, 5.2A-W, 5.2E-W, 6.2A-W, 3.3S-W, 5.3A-W, 6.3A-2, and 6.3E-2
Micrologic trip units. See the catalog numbers and references beginning in Table 17.
The mission critical trip units have the same settings and trip curves as the standard trip units as
described in this document.
For more information see the trip unit user guides 48940-310-01 and 48940-312-01 on the Schneider
Electric website.

Accurate Measurements for Complete Protection
PowerPact H-, J-, and L-frame circuit breakers devices offer excellent measurement accuracy from
15 amperes on up to the short-circuit currents. This is made possible by a new generation of current
transformers combining “iron-core” sensors for self-powered electronics and “air core” sensors
(Rogowski coils) for measurements. The protection functions are managed by an ASIC (Application
Specific Integrated Circuit) component that is independent of the measurement functions. This
independence ensures immunity to conducted and radiated disturbances and increases reliability.
Numerous Security Functions
Torque-limiting screws
The screws secure the trip unit to the circuit breaker. When the correct tightening torque is
reached, the screw heads break off. Optimum tightening avoids any risk of temperature rise. A
torque wrench is no longer required.
Easy and sure changing of trip
units
All trip units are interchangeable, without wiring. A mechanical mismatch-protection system
makes it impossible to mount a trip unit on a circuit breaker with a lower rating.
“Ready” LED for a continuous
self-test
The LED on the front of the electronic trip units indicates the result of the self-test running
continuously on the measurement system and the tripping release. As long as the green LED is
flashing, the links between the CTs, the processing electronics and the tripping mechanism are
operational. The circuit breaker is ready to protect. A minimum current of 15 to 50 A, depending
on the device, is required for this indication function.
A patented dual adjustment
system for protection functions.
Available on Micrologic 5 / 6 trip units, the system consists of:
an adjustment using rotary switches sets the maximum value
an adjustment using the keypad or made remotely, fine-tunes the setting. This setting may
not exceed the first one. It can be read directly on the Micrologic trip unit screen, to within
one ampere and a fraction of a second.

Section 3—Circuit Breakers
Dual-Break Rotating Contacts
All PowerPact™ H-, J-, and L-frame circuit breakers are equipped with dual-break rotating contacts
that reduce the amount of peak current during a short circuit fault. This reduces the let-through
currents and enhances equipment protection.
Reduced Let-Through Currents
The moving contact has the shape of an elongated “S” and rotates around a
floating axis. The shape of the fixed and moving contacts are such that the
repelling forces appear as soon as the circuit reaches approximately 15 times I
n
.
Due to the rotating movement, repulsion is rapid and the device greatly limits
short-circuit currents, whatever the interrupting level of the unit (D, G, J or L). The
fault current is extinguished before it can fully develop. Lower let-through currents
provide less peak energy, reducing the required bus bar bracing, lowering
enclosure pressure, and delivering improved series or combination ratings. See
page 23 for UL Current Limiting labels.
High Ampere Interrupting Ratings (AIR)
Circuit breakers are available with interrupting ratings up to:
200 kA at 240 Vac delta
200 kA at 480 Vac delta
100 kA at 600 Vac delta.
See Table 1 for additional performance levels.
Internal Operating Mechanism
PowerPact H-, J-, and L-frame circuit breakers have an over-center toggle mechanism providing quick-
make, quick-break operation. The operating mechanism is also trip-free, which allows tripping even
when the circuit breaker handle is held in the “ON” position.
Internal cross-bars provide common opening and closing of all poles with a single operating handle.
All PowerPact circuit breakers have an integral push-to-trip button in the cover to manually trip the
circuit breaker. This should be used as part of a regular preventive maintenance program.

Handle Position Indication
The circuit breaker handle can assume any of three positions, ON, tripped or OFF as shown. The
center tripped position provides positive visual indication that the circuit breaker has tripped.
The circuit breaker can be reset by first pushing the handle to the extreme “OFF” position. Power can
then be restored to the load by pushing the handle to the “ON” position.
Circuit Breaker Ratings
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
Table 8: Circuit Breakers on page 19 and on the faceplate label on the front of the circuit breaker.
Reverse Feeding of Circuit Breakers
The standard unit-mount H-, J-, and L-frame circuit breakers have sealed trip units and may be reverse
fed. See Tables 14–15 and 28–36 for catalog numbers.
Circuit breakers with field-interchangeable trip units (designated by the suffix T and labeled “LINE” and
“LOAD”) cannot be reverse fed. Neither can circuit breaker frames without terminations or trip units.
Current Limiting
The current limiting attributes of PowerPact H-, J-, and L-frame circuit breakers provide greater
protection for downstream devices by limiting the let-through current in the event of a fault. The
current-limiting capabilities of HJ/HL/HR, JJ/JL/JR, and LJ/LL/LR frame circuit breakers are
documented with Underwriters Laboratories and Canadian Standards Association. These current-
limiting circuit breakers ship with a label that identifies them as UL/CSA Current Limiting Circuit
Breakers. (The HD/HG, JD/JG, and LD/LG circuit breakers do not carry the UL Current Limiting label).
The trip curves with let-through data are available in the trip curve section in this catalog.
Please note that as let-through curves for UL Listed/CSA Certified Current-Limiting Circuit Breakers,
these curves are maximum let-through values.
100% Rated
Some models of the H-, J-, and L-frame circuit breakers are UL Listed/CSA Certified to be applied at
up to 100% of their current rating. Because of the additional heat generated, the use of specially-
designed enclosures, copper lugs on H- and J-frame circuit breakers, and 194°F (90°C) rated wire is
required when applying circuit breakers at 100% of continuous current rating. (L-frame circuit breakers
can use aluminum or copper lugs.) Markings on the circuit breaker indicate the minimum enclosure
size and ventilation required. The 194°F (90°C) wire must be sized according to the ampacities of the
167°F (75°C) wire column in the NEC. Circuit breakers with 100% rating can also be used in
applications requiring only standard (80%) continuous loading.

Special Applications
Protection of Industrial Control Panels
PowerPact H-, J-, and L-frame circuit breakers are also used in industrial control panels. They serve as
an incoming devices or can be combined with contactors to protect motor feeders:
compliance with worldwide standards including IEC 60947-2 and UL 508 / CSA C22.2 N°14
overload and short-circuit protection
installation in universal and functional type
PowerPact H-, J-, and L-frame circuit breakers equipped for motor protection functions as described in
the following pages can be used in industrial control panels. The accessories for the PowerPact H-, J-,
and L-frame circuit breakers are suitable for the special needs of these applications.
400 Hz Applications
Micrologic™ 3.2/3, 5.2/3 A or E and 6.2/3 with A or E measurement functions are suitable for 400 Hz.
The use of electronics offers the advantage of greater operating stability when the frequency varies.
However the units are still subject to temperature rise caused by the frequency.
The practical consequences are:
limit settings: see the I
r
derating table below
the long-time, short-time and instantaneous pick-ups are not modified (see pages 62 or 64)
the accuracy of the displayed measurements is 2% (class II).
Auxiliary Switch (OF) in 400 Hz Networks
Shunt Trip (MX) or Undervoltage Trip (MN) Voltage Release at 400 Hz and 440 V
For circuit breakers on 400 Hz systems, only 125 Vdc undervoltage trip (MN) or shunt trip (MX) releases
may be used. The release must be supplied by the 400 Hz system through a rectifier bridge (to be selected
from the table below) and an additional resistor with characteristics depending on the system voltage.

Section 4—Automatic Switches
Automatic Switch Functions
An automatic switch can be used to open and close a circuit under normal operating conditions. They
are similar in construction to circuit breakers, except that the switches open instantaneously at a factory-set,
non-adjustable trip point calibrated to protect only the molded case switch.
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.
PowerPact™ H-, J-, and L-frame automatic switches are available in unit mount, I-Line™, plug-in and
drawout versions. They use the same accessories and offer the same connection possibilities as the
circuit-breaker versions. They may be interlocked with another switch or circuit breaker to form a
source-changeover system.
Switches are Listed under UL file E103740 and Certified under CSA file LR88980.
Motor Operator
PowerPact H-, J-, and L-frame switches equipped with a motor operator module allow remote closing
and opening.
Ground Fault Protection (H- and J-Frame Circuit Breakers Only)
An ELM or GFM module may be added to an automatic switch to monitor all leakage currents in the
outgoing circuits of the equipment on which the automatic switch is installed. When the ELM or GFM
module detects an earth-leakage current, the automatic switch interrupts the load current.
Automatic Switch Protection
The automatic switch can make and break its rated current. For an overload or a short-circuit, it must
be protected by an upstream device, in compliance with installation standards. Due to their high-set
instantaneous release PowerPact H-, J- and L-frame automatic switches are self-protected.

Motor Circuit Protection

Section 5—Motor Circuit Protection
General Information
The parameters to be considered for motor-feeder protection depend on:
the application (type of machine driven, operating safety, frequency of operation, etc.)
the level of continuity of service required by the load or the application
the applicable standards for the protection of equipment.
The required electrical functions are:
isolation
switching, generally at high endurance levels
protection against overloads and short-circuits, adapted to the motor
additional special protection.
A motor branch circuit must comply with the requirements of standard UL 508 concerning contactors
and their protection:
coordination of feeder components
overload relay trip classes.
Motor Branch Circuit Protection Function
A motor branch circuit comprises a set of devices for motor protection and control, as well as for
protection of the branch circuit itself.
Switching
The purpose is to control the motor (ON / OFF), either manually, automatically or remotely, taking into
account overloads upon start-up and the long service life required. This function is provided by a
contactor. When the coil of the contactor's electromagnet is energized, the contactor closes and
establishes, through the poles, the circuit between the upstream supply and the motor, through the
circuit breaker.
Basic Protection
Short-circuit protection
Detection and breaking, as quickly as possible, of high short-circuit currents to avoid damage to the
installation. This function is provided by a circuit breaker.
Overload protection
Detection of overload currents and motor shutdown before temperature rise in the motor and
conductors damages insulation. This function is provided by a circuit breaker or a separate motor
overload relay.
Phase unbalance or phase loss protection
Phase unbalance or phase loss can cause temperature rise and braking torques that can lead to
premature aging of the motor. These effects are even greater during starting, therefore protection
must be virtually immediate.

Additional Electronic Protection
Locked rotor
Under-load
Long starts and stalled rotor
Insulation faults
Trip Class of a Overload Relay Device
The motor branch circuit includes thermal protection that may be built into the circuit breaker. The
protection must have a trip class suited to motor starting. Depending on the application, the motor
starting time varies from a few seconds (no-load start) to a few dozen seconds (high-inertia load).
Example: In class 20, the motor must have finished starting within 20 seconds (6 to 20 s) for a starting
current of 6 x FLA.
Asynchronous-Motor Starting Parameters
The main parameters of direct on-line starting of three-phase asynchronous motors (90% of all
applications) are listed below.
FLA: Full load amperes
This is the current drawn by the motor at full rated load.
Id: locked rotor current
This is the current drawn by the motor during starting, on average 6.0 x In for a duration of 5 to 30
seconds depending on the application. These values determine the trip class and any additional
“long-start” protection devices that may be needed.
Id: peak starting current
This is the subtransient current during the first two half-waves when the system is energized, on the
average 14 I
n
for 10 to 15 ms (e.g. 1840 A peak).
The protection settings must effectively protect the motor, notably through a suitable overload relay trip
class, but let the peak starting current through.
Motor-Feeder Solutions
PowerPact™ H-, J-, and L-frame circuit breakers motor circuit breakers are designed for motor-feeder
solutions using:
three devices, including an electronic MCP or 1.3 M instantaneous-only trip unit
two devices including a 2 M electronic trip unit.

Electronic Motor Circuit Protectors (AC Only)
PowerPact H- and J-frame Electronic Motor Circuit Protectors (MCP) are instantaneous-trip circuit
breakers. They are designed to offer short circuit protection and are National Electrical Code
®
(NEC
®
)
compliant when installed as part of a combination controller having motor overload protection. MCP
circuit breakers accept the same accessories and terminals as the equivalent thermal-magnetic circuit
breakers. (See Section 3 for Accessories.)
The unique design of the PowerPact MCPs includes two rotary switches to allow quick setting
adjustments based on the characteristics of the motor.
The first rotary switch allows for Full Load Amperes (FLA) adjustment across the range of the frame size.
The second rotary switch selects the type of motor protection based on Automatic 1 for Standard
Efficiency or Automatic 2 for High Energy Efficient. When using the automatic settings the MCP
microprocessor automatically adjusts the trip settings for both current and time to align with the start-up
characteristic for the motor type, whether it is a standard or energy-efficient motor. This includes a
dampening means to accommodate a transient motor in-rush current without nuisance tripping of the
circuit breaker. Rotary switch 2 also allows for traditional motor protection from 8 to 13 times the
selected FLA.
The MCP rotary switches are detented and allow the device to be set to specific trip values within a
typical accuracy range of +/-5%.
Full Load Amp Settings
1. Determine the motor’s full-load current by referring to the nameplate on the motor.
2. Set the trip range by turning the FLA rotary switch to the setting closest to the motor’s full load
current.
Automatic Protection Settings
The MCP microprocessor automatically adjusts the trip settings for both current and time to align with
the start-up characteristics for the motor type selected. This includes a dampening means to
accommodate a transient motor in-rush current without nuisance tripping of the circuit breaker.

Additional Technical Characteristics
Table 51: Additional Technical Characteristics
Phase unbalance
An unbalance in three-phase systems occurs when the three
voltages are not equal in amplitude and/or not displaced 12
with respect to each other. It is generally due to single-phase
loads that are incorrectly distributed throughout the system and
unbalance the voltages between the phases.
These unbalances create negative current components that
cause braking torques and temperature rise in asynchronous
machines, thus leading to premature aging.
Phase loss
Phase loss is a special case of phase unbalance.
During normal operation, it produces the effects mentioned
above and tripping must occur after four seconds.
During starting, the absence of a phase may cause motor
reversing, i.e. it is the load that determines the direction of
rotation. This requires virtually immediate tripping (0.7
seconds).
Starting time in compliance with the class (Micrologic 2 M)
For normal motor starting, Micrologic 2 M checks the conditions
below with respect to the thermal-protection (long-time) pick-up
FLA:
current > 10% x FLA (motor-off limit)
overrun of 1.5 x FLA threshold, then return below this
threshold before the end of a 10 s time delay.
If either of these conditions is not met, the thermal protection
trips the device after a maximum time equal to that of the
selected class. Pick-up FLA must have been set to the current
indicated on the motor rating plate.

Section 6Trip Units
Available Trip Units
PowerPact™ H-, J-, and L-Frame circuit breakers offer a range of thermal-magnetic and
Micrologic™ electronic trip units in interchangeable cases. Thermal-magnetic trip units are
designed to open automatically under overload or short circuit. H-frame and J-frame thermal-
magnetic circuit breakers contain individual thermal (overload) and instantaneous (short circuit)
sensing elements in each pole.
Micrologic electronic trip units provide intelligent operation, with wide setting ranges make
installation upgrades easier. Designed with processing capabilities, Micrologic trip units can
provide measurement information and device operating assistance to supply all of the information
required to manage the electrical installation and optimize energy use.
Micrologic trip units offer excellent measurement accuracy, using a new generation of current
transformers combining “iron-core” sensors for self-powered electronics and “air-core” sensors
(Rogowski coils) for measurements. The protection functions are managed by an ASIC component
that is independent of the measurement functions. This independence ensures immunity to
conducted and radiated disturbances and a high level of reliability.
An LED on the front of the electronic trip units indicates the result of the self-test running continuously on
the measurement system and the tripping release. When the green LED is flashing, the links between
the CTs, the processing electronics and the Mitop release are operational. The circuit breaker is ready
to protect. A minimum current of 15 to 50 A, depending on the device, is required for this function.
The dual adjustment for protection functions on Micrologic 5 / 6 consists of:
an adjustment using rotary switches sets the maximum value
an adjustment, made using the keypad or remotely, fine-tunes the setting. This setting may not
exceed the first one. It can be read directly on the Micrologic screen, to within one ampere and
a fraction of a second.
NOTE: All the trip units have a transparent sealable cover that protects access to the adjustment
rotary switches.

Micrologic 3 Trip Units
Micrologic 3 trip units can be used on PowerPact H-, J-, and L-Frame circuit breakers with performance
levels D/G/J/L.
They provide:
standard protection of distribution cables
indication of:
overloads (using LEDs)
overload tripping (using the SDx relay module).
Circuit breakers equipped with Micrologic 3 trip units can be used to protect distribution systems
supplied by transformers.
Protection
Settings are made using the adjustment rotary switches.
Overloads: Long time protection (I
r
)
Inverse time protection against overloads with an adjustable current pick-up I
r
set using a rotary switch
and an adjustable time delay t
r
.
Neutral protection
On 3-pole L-frame circuit breakers, neutral protection is not possible.
On four-pole L-frame circuit breakers, neutral protection may be set using a three-position switch:
switch position 4P 3D: neutral unprotected
switch position 4P 3D + N/2: neutral protection at half the value of the phase pick-up, (0.5 x I
r
)
switch position 4P 4D: neutral fully protected at I
r
Indicators
Front indicators
The green “Ready” LED blinks slowly when the electronic trip unit is ready to provide protection. It
indicates the trip unit is operating correctly.
Orange overload pre-alarm LED: steady on when I > 90% I
r
Red overload LED: steady on when I > 105% I
r
Remote indicators
An overload trip signal can be remotely checked by installing an SDx relay module inside the circuit
breaker. This module receives the signal from the Micrologic electronic trip unit through an optical link
and makes it available on the terminal block. The signal is cleared when the circuit breaker is reclosed.

Power Requirements
The amount of current needed to power the trip unit is printed in the upper left hand corner of the trip
unit by the Ready LED.
Protection
Settings can be adjusted in two ways, using the rotary switches and/or the keypad.
The keypad can be used to make fine adjustments in 1 A steps below the maximum value defined
by the setting on the rotary switch.
Access to setting modifications using the keypad is protected by a locking function displayed on the
screen and controlled by a microswitch.
The lock is activated automatically if the keypad is not used for 5 minutes.
Access to the microswitch is protected by a transparent, sealable cover.
With the cover closed, it is still possible to display the various settings and measurements using the
keypad.
Overloads: Long-Time Protection (I
r
)
Inverse time protection against overloads with an adjustable current pick-up I
r
is set using a rotary
switch or the keypad for fine adjustments. The time delay t
r
is set using the keypad.
Short-Circuits: Short-Time Protection (I
sd
)
Short-circuit protection with an adjustable pick-up I
sd
and adjustable time delay t
sd
, with the possibility
of including a portion of an inverse time curve (I
2
t On).
Short-Circuits: Instantaneous Protection (I
i
)
Instantaneous protection with adjustable pick-up I
i
.
Additional Ground Fault Protection (I
g
) on Micrologic 6 Trip Units
Residual type ground-fault protection with an adjustable pick-up I
g
and adjustable time delay t
g
.
Possibility of including a portion of an inverse time curve (I
2
t On).
Neutral Protection
On 4-pole circuit breakers, this protection can be set using the keypad:
Off: neutral unprotected
0.5: neutral protection at half the value of the phase pick-up (0.5 x I
r
)
1.0: neutral fully protected at I
r
OSN: Oversized neutral protection at 1.6 times the value of the phase pick-up.
Used when there is a high level of 3rd order harmonics (or orders that are multiples of 3) that
accumulate in the neutral and create a high current. In this case, the device must be limited to
I
r
= 0.63 x I
n
for the maximum neutral protection setting of 1.6 x I
r
.
With 3-pole circuit breakers, the neutral can be protected by installing an external neutral sensor
with the output (T1, T2) connected to the trip unit.

g
) protection, without a time delay. For
PowerPact H- and J-frame circuit breakers, the ZSI function is available only in relation to the
upstream circuit breaker (ZSI out). For PowerPact L-frame circuit breakers, the ZSI function is
available in relation to the upstream circuit breaker (ZSI out) and downstream circuit breakers (ZSI in).

This module receives the signal from the Micrologic electronic trip unit through an optical link and
makes it available on the terminal block. The signal is cleared when the circuit breaker is closed.
Note: all the trip units have a transparent sealable cover.
These outputs can be reprogrammed to be assigned to other types of tripping or that protects access
to the adjustment rotary switch. The module is described in detail in the section dealing with
accessories.
