Remote Control Operation
The remote-control capability of
the breaker is “armed” when the
breaker handle is manually switched
to the “ON” position. Once armed,
the breaker can be pulsed “ON” and
“OFF” by a controller device which
provides an ac pulse of specified
magnitude and duration to the sole-
noid operated mechanism. Control
connections to the breaker are pro-
vided through a male conductor
plug (supplied by others) which
snaps into the female connector
provided with the breaker.
A normally open (a) auxiliary con-
tact provides for breaker “ON”/“OFF”
status indication to the remote
controller and/or indicating lamp.
The remote-control capability of the
breaker is “disarmed” when the
breaker handle is in the “OFF” or
“TRIPPED” position. In the event
the breaker automatically trips, the
breaker must be reset manually.

Description
UL 1077 Supplementary Protectors
Type SPCL Supplementary Protec-
tors are IEC circuit breakers that are
recognized by UL under UL 1077.
They are intended for use as over-
current protection within an appli-
ance or electrical equipment where
branch circuit protection (for exam-
ple a UL listed Molded Case Circuit
Breaker) has already been provided
or is not required.
Equipment and Control
Circuit Protection
These protectors are ideal for replac-
ing fuses in control circuits. Applica-
tions include protecting motor
control circuits, small control circuit
transformers, relays, contactor coils,
power supplies, PLC I/O points, appli-
ances, and electronic equipment.
Product Features
The Type SPCL Supplementary
Protectors are provided in light gray
cases with charcoal gray handles.
DIN-Rail Mounting: A quick snap-on
clip design allows easy installation
on 35mm DIN Rail.
Current-Limiting Design: Fast short
circuit interruption reduces let-
through energy, reducing damage
to the circuit.
Thermal-Magnetic Overcurrent
Protection: Types B and C overcur-
rent curves provide maximum
reliability and accuracy. Type B
protection is normally used for low
inrush applications. Type C protec-
tion is used for general purpose
industrial applications that require
higher inrush tolerance.
Center Trip Position: The breaker
handle has a unique center trip
“Reset” position that indicates an
overcurrent trip. “Off” (O) and “On”
(I) handle positions are visually indi-
cated by red and green flags.

Description
UL 1077 Supplementary Protectors
Type SPHM Supplementary Protec-
tors are IEC circuit breakers that are
recognized by UL under UL 1077.
They are intended for use as over-
current protection within an appli-
ance or electrical equipment where
branch circuit protection (for exam-
ple a UL listed Molded Case Circuit
Breaker) has already been provided
or is not required.
Equipment and Control Circuit
Applications
These protectors are ideal for protect-
ing motor control circuits, CPTs,
relays, contactor coils, power supplies,
PLC I/O points, lighting circuits, appli-
ances, electronic equipment, and
replacing fuses.
Product Features
The Type SPHM Supplementary Pro-
tectors are provided in light gray cases
with charcoal gray handles. Handles
are marked with “O” for “Off” and “I”
for “On”.
DIN Rail Mounting: Easy installation
on 35mm DIN Rail. A spring loaded
clip is provided for quick release
from the DIN Rail mounting.
Heat-Induced Nuisance Tripping
Eliminated: The protector is designed
to “hold in” at 100% of continuous
rated current regardless of ambient
temperatures from -40 to +85°C.
Immediate Reset After Trip: The pro-
tector can be reset (closed) immedi-
ately after an overcurrent trip
without a “cooling off” period.
Precise Overcurrent Calibration: The
protector can be precisely calibrated
to a wide variety of current ranges
from 0.1 to 50 amperes continuous.
For special ratings not shown, con-
tact Cutler-Hammer.

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. Except as noted,
terminals comply with Underwriters
Laboratories, Inc., Standards UL486A
and UL486B. Unless otherwise
specified, F-frame circuit breakers
are factory equipped with load ter-
minals only.
Ordering Information
F-frame circuit breakers and molded
case switches have load terminals
only as standard equipment. When
standard line-end terminals (same as
standard load-end terminals) are
required, add suffix L to the circuit
breaker catalog number. When non-
standard or optional line and/or load
terminals are required, order by
style number. Specify if factory
installation is required.

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. All terminals comply
with Underwriters Laboratories, Inc.,
Standards UL486A and UL486B
and CSA Standard C22.2 No. 65,
or Electrical Bulletin 1165. Unless
otherwise specified, J-frame circuit
breaker line and load terminals are
shipped separately for field
installation.
The bottom of the standard
TA250KB terminal contains a recess
which is positioned over the J-frame
circuit breaker terminal conductor.
Ordering Information
J-frame circuit breakers use Cu/AI
terminals as standard. When
optional copper-only terminals are
required, order by catalog number.

Line and Load Terminals
Line and load terminals provide wire
connecting capabilities for specific
ranges of continuous current ratings
and wire types. All terminals comply
with Underwriters Laboratories, Inc.,
Standards UL486A and UL486B
and CSA Standard C22.2 No. 65M.
Unless otherwise specified, L-frame
circuit breaker line and load termi-
nals are shipped separately for field
installation.
The wire connecting terminal is
secured with two pan-head, slotted
screws and lock washers which can
be checked for the correct torque
loading or retightened from the
front of the circuit breaker before
installation of the conductors.
(Applies to all styles.) The circuit
breaker line/load terminal conduc-
tors are positioned in the conducting
holes in the wire connecting terminal
and are secured with recessed socket
screws which are tightened to the
correct torque loading from the front
of the circuit breaker.
Ordering Information
L-frame circuit breakers use Cu/AI
terminals as standard. When optional
copper terminals are required, order
by catalog number. Specify if factory
installation is required.
