required) are available as separate catalog items.
NOTE: Accessory installation must be completed
before the circuit breaker is mounted and connected.
(See installation instructions supplied with accessory
before proceeding).
NOTE: Accessories manufactured by Siemens Energy and Automation, Inc. that are suitable for use
with Circuit Breaker Types ED2, ED2Y, ED4, ED6,
HED4 and HED6 are also suitable and may be used
with T ypes HHED6 and HCED6.
A. Turn of f and lock out all power before installing or
servicing.
B. Make sure that the circuit breaker is suitable for
the installation by comparing nameplate ratings
with system requirements. Inspect the circuit
breaker for completeness and check for any damage before mounting.
C. The circuit breaker must be in the “Tripped” or
“OFF” position prior to mounting.

steps:
1. For individual enclosures, panelboards and
switchboards manufactured by Siemens Energy
and Automation, Inc., follow the instructions provided with this equipment.
2. For those applications where mounting is on a
flat surface of the customers equipment, drill
and tap mounting bolt holes according to the
drilling plan in Fig. 2. For handle escutcheon
cut out plans refer to Fig. 2.
NOTE: For mounting single pole breakers, the use
of a back mounting plate (Catalog Number E2BMB)
is required.

sure terminals can be connected when the
circuit breaker is mounted.

6. After mounting the circuit breaker, line and load
terminals and accessory terminals should be
connected. Install wire connectors with correct
torque requirements. T orque values for line and
load connectors are provided on the circuit
breaker nameplate. Insure that wire and wire
connectors are fully engaged on terminals and
that connectors are flush with end of terminal.
NOTE: When aluminum conductors are used,
the application of a suitable joint compound is
recommended to reduce the possibility of
terminal overheating.
NOTE: Circuit Breaker Types HHED6 and
HCED6 have load terminals that can rotate
between two positions. When installing wire connectors, the load terminal must be positioned
at an angle as shown in Fig. 3.
7. After the circuit breaker is installed, check all
mounting hardware for secureness.

3. Manual Operation
Manual operation of the circuit breaker is controlled
by the circuit breaker handle and the PUSH-TOTRIP 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 position. (See Fig. 4)

Handle
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.
NOTE: In the event of a thermal trip, the circuit
breaker cannot be reset until the thermal element cools.
B. PUSH-TO-TRIP Button
The PUSH-TO-TRIP button checks the tripping
function and is used to manually exercise the
operating mechanism. (PUSH-TO-TRIP button
not provided on switch)
4. Inspection and Field Testing
ED-frame circuit breakers are designed to provide
years of maintanance free service. The following
procedure outlines how to inspect and test a circuit
breaker in service.
Inspection and Maintenance
Circuit breakers in service should be inspected
periodically. The inspection should include the
following steps:
A. Turn of f and lock out power before inspecting or
servicing. Special attention should be paid to
reverse feed applications to ensure no voltage is
present.
B. Remove dust, soot, grease or moisture from the
surface of the circuit breaker using a lint free cloth
brush or vacuum cleaner. DO NOT blow debris
into the circuit breakers. If contamination is found,
eliminate the source of the problem.
NOTE: Do not spray or allow any petroleum based
chemicals, solvents or paints to contact the inside
or outside of breaker or electrical connections.

C. Switch the circuit breaker to the ON and OFF
positions several times to be sure the mechanical linkages are free and do not bind. If
mechanical linkages are not free, replace the
circuit breaker.
D. Press the PUSH-TO-TRIP button to mechani-
cally trip the circuit breaker . Trip, reset, and switch
the breaker on several times. If the circuit breaker
cannot be turned on replace the circuit breaker.
E. Check circuit breaker housing and handle for
cracks, chipping and discoloration. Circuit breakers should be replaced if cracks or severe discoloration is found.
F. Check terminals and wire connectors for loose-
ness or signs of overheating. Overheating will
show as discoloration, melting or blistering of conductor insulation, or as pitting or melting of conductor surfaces due to arcing. If there is no evidence of overheating or looseness, do not disturb or tighten the connections. If there is evidence of overheating, terminations should be
replaced. Before re-energizing the circuit breaker,
all wire connectors and cable should be refurbished to the original installed condition.
IMPORTANT: Refer to instructions on page 2,

Turn off and lock out all
power before installing or

G. Check circuit breaker mounting hardware.
Tighen if necessary.
H. Check area where circuit breaker is installed for
any safety hazards, including personal safety
and fire hazards. Exposure to certain types of
chemicals can cause deterioration of electrical
connections.
Field T esting
Any field testing should be conducted in accor-
dance with NEMA Standards Publication AB2.
5. Adjustment procedures for ETI Motor Circuit
Interrupter.
A. Determine the Motor Full Load Amperes from
the motor nameplate or table 430-150 of N.E.C.
(1990).
B. Use T able 1 for suggested device catalog num-
ber and adjustment setting.
C. Adjust the instantaneous button by rotating to the
desired setting determined above (Ref. Fig. 5).
ETI instantaneous-trip circuit breakers are recommended for use in combination motor starters to provide selective short-circuit protection for the motor
branch circuit. The adjustable instantaneous-trip feature of the ETI circuit breaker provides for a trip setting slightly above the peak motor-inrush current. With
this setting, no delay is introduced in opening the circuit when a fault occurs. This circuit breaker has no
time-delay trip element. Therefore it must be used in
conjunction with, and immediately ahead of, the
motor-running overcurrent protective device.
The recommended ETI instantaneous only circuit
breakers listed in T able 1 have continuous-current ratings of at least 1 15% of motor full-load currents. The
trip-setting positions are approximately 11 times motor
full-load currents. The suggested trip settings, and in
some cases, the allowable maximum setting of 1300%
of motor full load current may not be sufficient to get
“energy efficient” motors on line.
