GEI-50299
Power Circuit Breakers Types AK-2-15 and AK-2/3-25
a rod against a trip paddle of the trip shaft,
rotating it, and causing the mechanism trip latch
to be displaced.
This allows the mechanism
linkage to collapse through the action of the
mechanism operating springs.
solenoid connecting link and manual cam connecting
link are both connected to the closing spring pin
at the top of the mechanism, thus compressing
the springs when force is provided by either
means of breaker closing.
CAUTION:
If
the breaker is tripped manually
while the operating handle is in the reset position,
the handle should be lowered by the right hand
while operating the trip button with the left hand.
The breaker is manually closed by rotating
the closing handle
90
degrees counterclockwise.
No reset stroke is necessary as is the case with
the standard manual breaker.
Electrical closing
may be performed either locally or remotely in
the same manner as the standard electrical breaker.
ELECTRICAL WITH MANUAL OPERATION
This operating mechanism provides both man
ual and electrical closing. The operating mech
anism is similar to the mechanism of the standard
electrical breaker with the addition of the manual
handle, cam and mechanism connecting link. The
Tripping is accomplished by the manual trip
button on the escutcheon or by any of the electrical
tripping devices available for use on the standard
breakers.
