INTRODUCTION
The JM and LM Frame circuit breaker line includes
JM6 and LM6 circuit breaker types. These circuit
breakers are rated for operating voltages up to 600
VAC, 50/60 Hz.
INSTALLATION
JM and LM Frame circuit breakers are for use in
individual enclosures, panelboards, switchboards
or other approved equipment.
The installation procedure consists of inspecting,
attaching required accessories, mounting the
circuitbreakerandconnectingandtorquing the line
and load wire connectors.
Mounting hardware and unmounted wire connectors
(where required) are available as separate catalog
items.
A. Turn off and lock out all power before installing
or servicing this circuit breaker.
Fig. 1
B. Make sure that the device is suitable for the
installationby comparing nameplate ratingswith
systemrequirements. Inspect the circuitbreaker
for completeness and check for any damage
before mounting.
C. Device must be in “TRIPPED” or “OFF” position
prior to mounting. See Fig. 4.

D. Tomount the deviceperform the followingsteps:
1. For individual enclosures, panelboards and
switchboards manufactured by Siemens
Energy & Automation, Inc., follow the
instructions provided with this equipment.
2. For those applications where mounting is on
aflat surfaceofthe customersequipment,drill
and top mounting bolt holes according to the
drilling plan in Fig.2. For escutcheon cut out
plans refer to Fig. 3.
3. If device contains internal accessories, make
sure terminals can be connected when the
circuit breaker is mounted.

4. Remove the line and load terminal shields
(see Fig. 4) by loosening the shield screws
that attach them to the circuit breaker.
5. Position the circuit breaker on the mounting
surfaces, install the mounting hardware and
tighten securely.
6. After mountingthe circuit breaker,the line and
load terminal accessory terminals should be
connected.
7. After the circuit breaker is installed, check all
mounting hardware for secureness. Check
wireconnectorsforcorrecttorquerequirements.
Torque values for line and load connectors are
provided on the circuit breaker nameplate.

MANUAL OPERATION
Manualoperationofthe circuit breakeris controlled
by the circuit breaker handle and the PUSH-TO-
TRIP button. The circuit breaker handle has three
indicating positions, two of which are molded into
the handle to indicate ON and OFF. The third
position indicates a TRIP position and is between
the ON and OFF positions.(See Fig. 4)
A. Circuit Breaker Reset
After tripping, the circuit breaker is reset by
moving the circuit breaker handle to the reset
position and then moving the handle to the ON
position.
B. The PUSH-TO-TRIP Button
The PUSH-TO-TRIP button checks the tripping
function and is used to manually exercise the
operating mechanism.

ELECTRONIC OPERATION
The setting dials on the face of the electronic trip
unit are rotary switches that must be properly set
to mechanical detent (click stop) positions. An
improper switch setting will cause the trip unit to
default (as a fail safe condition) to the lowest
permissive setting and, consequently, may result
in unintentional or nuisance tripping.
Continuous Current (lr) and Long Time Delay
All models have a Continuous Current and Long
Time Delay adjustment. This single knob adjusts
theContinuousCurrent setting ofthe circuit breaker
and sets the LongTime Delay. This setting (lr) is a
percentage of the Maximum Continuous Current
rating (ln). Two long time delay settings are
available. These are delay times of 3 seconds or
25 seconds at 6 times the Continuous Current
Setting (lr). These are selected by using the
appropriate area of the setting. See Figure 5.
Instantaneous Pickup

ThisadjustmentsetstheInstantaneousPickup of the
circuit breaker. The settings are multiples of the
Continuous Current Setting (lr).
Thesedeviceshaveafixedinstantaneousoverrideof
approximately 10.5 times the Maximum Continuous
Current rating (ln) of the circuit breaker. When set to
“MAX” the Instantaneous Pickup defaults to the
instantaneous override value. See Figure 6.
Maintenance
JM and LM frame circuit breakers are designed to
provide years of maintenance free service.
Experiencehasshownthat properlyappliedmolded
case circuit breakers normally do not require
maintenance. However, some industrialusersmay
chooseto establishan inspection and maintenance
procedure to be carried out on a regular basis. For
detailed information, consult applicable NEMA
publication or your local Siemens sales office.
NOTE: Do not spray or allow any petroleum based
chemicals,solventsor paints to contact the molded
parts or nameplates.
