CEP7 Solid State
Overload Relays
Advanced solid state
motor protection
e introduction of the second genera-
tion of CEP7 solid state overload relays
advances Sprecher + Schuh’s leading edge
technology with several improved fea-
tures. is second generation of CEP7
overload relay includes features like:
• Selectable trip class and eld
installable modules
• A wider (5:1) set current
adjustment range
• A more robust mechanical and
electrical mounting
• Self-sealed latching mechanism
e basic concept of utilizing Ap-
plication Specic Integrated Circuits
(ASICs) resulting in an aordable
solid state overload relays remains
unchanged. is kind of versatility and
accuracy was simply not possible with
traditional bimetallic or eutectic alloy
electromechanical overload relays.
Fewer units means greater
application flexibility
e CEP7 Soild State Overload is
available in three basic models:
• CEP7-ED1 is a Class 10, manual re-
set model available up to 45 amperes
which covers the most common
horsepower motors and your every
day application. is model is eco-
nomically priced to be competitive
with adjustable bimetallic overload
relays.
• CEP7-EE is full featured select-
able trip class (10, 15, 20 & 30)
3-phase application overload relay
with provision for eld mountable
modules to handle remote reset,
jam protection, and other modules
previously available only in higher
®
priced electronic overload relays.
Manual reset or automatic reset can
be selected with dip switches on the
CEP7-EE models.
• CEP7S-EE is a 1-phase application
overload relay packing all features of
the 3-phase CEP7-EE model.
Wide current
adjustment range
ermal or bimetallic overload relays
typically have a small current adjust-
ment range of 1.5:1 meaning that
the maximum setting is generally 1.5
times the lower setting. e rst gen-
eration of CEP7 caused the industry
to take note of the exibility when it
introduced a 3.2:1 adjustment ratio. A
wider adjustment range is the primary
reason the industry has been turn-
ing to more specications calling for
electronic overload relay protection
over thermal overload relays. Sprecher
+ Schuh building on eld experience
now introduces a CEP7 overload
capable of adjustment to a maximum
of ve times the minimum set current
which dramatically reduces the num-
ber of units required on-hand to cover
the full range of current settings up to
90 amperes.

CEP7 Overloads
Selectable tripping class
Because of today’s lighter T-frame mo-
tors, Class 10 overload relays (relays
that trip within 10 seconds of a locked
rotor condition) have become the
industry standard. If your application
requires a longer motor run-up time.
e CEP7-EE Selectable Trip Class
has DIP-switches providing Trip Class
selection of 10, 15, 20 or 30 seconds.
is ability allows you to closely match
the Trip Class with the run-up time of
the motor.
Choice of reset options
Most industrial applications usually
calls for an overload relay that must be
manually reset in the event of a trip.
is allows the cause of the overload
to be identied before
the motor is restarted. In
specialized cases, how-
ever, such as rooftop AC
units or where restarting
the motor will not harm
people or equipment,
automatic reset may
be desired. CEP7-ED1
overload relays are avail-
able with Manual Reset
exclusively which keeps
the cost down. CEP7-EE
models have a selectable dip switch in
Manual and Automatic Reset modes.
More robust design
e CEP7 has been re-designed to
physically extend to the back-pan
therefore aligning the mounting of
the overload with the corresponding
contactor. Further, the mechanical at-
tachment and direct electrical connec-
tion to the contactor has been “beefed-
up.” is provides for a more robust
mounting which means less damage
from shipping or during eld wire
installation. e bipolar latching relay
which controls the normally closed
trip contacts and normally open alarm
circuit contacts have been self-enclosed
therefore insolating the electromagnet
and shielding against airborne metal
particles and other potential environ-
mental debris. e CEP7 has been
tested to operate in -20° C. or up to
60° C (140 °F.) and withstand 3G of
vibration or 30G of shock on a moun-
tain up to an altitude of 2000m or in
a jungle at 95% humidity. Reliability
under every conceivable environmental
condition is a quality built into the de-
sign of this second generation of CEP7
electronic overload relay.
Self-powered design
means convenience
By developing the power it requires
from the applied voltage, the CEP7 is
“self-powered,” eliminating the need
for a separate control power source.
is is not the case with some other
competitive electronic overload relays.
Since the CEP7 is self-powered and a
traditional auxiliary contact is used to
interface with the contactor, the user
can apply the CEP7 the same way as
an electromechanical overload. No
special connections or control sche-
matic diagram provisions are required
in 3-phase applications.
Superior phase
failure protection
e CEP7’s on-board electronics are
constantly monitoring all three phases.
If the ASIC board senses that one
phase is missing during a steady state
running condition on a fully loaded
motor, it will trigger in 3 seconds. If a
single phase condition is present dur-
ing starting, the CEP7 will trip within
8 seconds (for a motor >80% loaded).
ese times are much faster than any
thermal bimetallic overload relay. In
addition, CEP7 overload relays detect
a 50% phase imbalance in the same
way as a phase loss.
CEP7 overload relays are available with
Class 10, 15, 20 or 30 tripping characteristics
Selectable DIP switch for:
• Manual versus automatic mode
• Trip class (10, 15, 20 or 30)

Additional Protection with
Side Mount Modules
e CEP7 oers a variety of eld
installable accessories for side mount
on the left side. Side mount modules
provide additional motor protection
functionality traditionally found only
on more expensive models. Modules
include the following additional
features.
• Remote Reset provision for reset
after trip from a remote pilot device
• Jam Protection/Remote Reset
provides adjustable Jam set points
and trip delay plus remote reset
• Ground Fault Protection/Remote
Reset combined with ground
fault current transformers provide
adjustable set points for ground
fault trip protection of equipment
plus remote reset
• Ground Fault/Jam Protection/
Remote Reset combines all three
features as described above
• PTC ermistor Relay/Remote
Reset manages thermistor sensor
signals from the motor
• Network Communication
Modules provide motor diagnostic
information via Probus or
Ethernet communication
- Two discreet Inputs and one
discreet Output
- Dierentiate between various
motor protection algorithms
- Overload and underload warning
- Jam protection
- Proactively alert maintenance
personnel just before or when a
fault occurs
- Plus remote reset
Conventional overload relays dissipate as much
as six watts of energy compared with as little as
150 milliwatts for the CEP7
Increased accuracy and
improved motor protection
Microelectronics provides exible and
accurate motor overload protection.
Unlike traditional overload relays
that simulate heat build-up in the
motor by passing current through
a heater element, CEP7 solid state
overload relays measure motor current
directly through integrated current
transformers. e transformers, in
turn, create a magnetic eld that
induces DC voltage onto the ASIC
board. e electronics identify
excessive current or loss of phase more
accurately, and react to the condition
with greater speed and reliability, than
traditional overload relays. In addition,
CEP7 solid state relays oer setting
accuracies from 2.5 – 5% and repeat
accuracy of 1%.
Dramatically lowered
energy requirement saves
money, reduces panel space
Because traditional overload relays
work on the principle of “modeling”
the heat generated in the motor
(recreating the heat in the bimetal
elements or heaters), a signicant
amount of energy is wasted. In
traditional bimetallic overload relays,
as many as six watts of heat are
dissipated to perform the protective
function. Because the CEP7 uses
sampling techniques to actually
measure the current owing in the
circuit, very little heat is dissipated in
the device…as little as 150 milliwatts.
is not only reduces the total amount
of electrical energy consumed in an
application, but it can also have a
dramatic impact on the design and
layout of control panels. e density
of motor starters can be much greater
because less heat is generated by each
of the individual components. Higher
density results in smaller control
panels. In addition, special ventilation
or air conditioning that might have
been required to protect sensitive
electronic equipment such as PLC’s
can now be reduced or eliminated.
CEP7 overload relays dramatically
reduced energy requirement saves
money and reduces panel space.

CEP7 Ground Fault Sensor Selection ➌
Ground fault current is sensed by passing all lines carrying current to and from a motor through
the window of a special current transformer called a ground fault sensor. If all the current to the
motor returns through the lines in the sensor window, no significant current will be induced in the
sensor secondary. If, however, ground fault current returns via a path external to the sensor, such
as via the conduit walls, a current will be induced in the sensor secondary. This current will be
sensed and amplified by solid state circuits. If the ground fault current is larger than the selected
ground fault trip level of the overload relay, the overload relay will trip.

Typical Wiring
for Single Phase Applications
CEP7 Single Phase Overload Relay
Must be connected as shown in Fig. 1 or 2 only.

Recommended connections
for CEP7S (i.e. 240V motors)
Fig. 2
Optional connections
for CEP7S (i.e. ≤120V motors)

➌ DO NOT USE
➊ Performance Criteria 1 requires the DUT to experience
no degradation or loss of performance.
➋ Environment 2.
➌ If the CEP7S is connected as shown in Fig. 3 the
overload will not trip! The CEP7S contains an electronic
circuit board that is self powered. If connected as
shown in Fig. 3, the CEP7S circuit board will not power
up and the CEP7S would not trip.
➍ Connecting a CEP7S in this manner powers the elec-
tronic circuit board. Connecting a 3-phase CEP7 in this
manner to handle 1-phase will NOT work.

➊ Dynamic inhibit: Protective function is enabled after the motor current goes above 150% and then falls below 125%.
➋The delay between the occurrence of a PTC out-of-range fault and a trip of the CEP7 varies, but is generally described by one of the following: a) 500 ms ± 250 ms, typi-
cal; or b) < 6 seconds, for a PTC out-of-range fault present at power-up of the side mount module. Under no conditions should a PTC trip take longer than 6 seconds.

CEP7-CBCT Ground Fault Trip Data
ATTENTION: The CEP7 Overload relay is not a ground fault circuit interrupter for personnel protection as defined in Article 100 of the NEC.
Ground fault trip delay: The delay between the occurrence of a ground fault and a trip of the CEP7 varies, but is generally described by one of the following:
50 ms ± 20 ms, typical
< 6 seconds, for a ground fault present at power-up of the side mount module
< 30 seconds, if the protection inhibit has not been cleared.
Under no conditions should a ground fault trip take longer than 31 seconds.
Dynamic inhibit: Protective function is enabled after the motor current goes above 150% and then falls below 125%.
Dimensions are in millimeters (inches). Dimensions not intended for manufacturing purposes.

• Dynamic inhibit on start. A unique circuit within the CEP7 Protection Modules monitors for motor
starting inrush current. The circuit inhibits the protection feature during the motor start period
and arms the protection function after the inrush current falls to motor rated current. This allows
the motor to start and run, avoiding nuisance tripping during the inrush period.
