Accessories For Drawout Breakers - GE WavePro LVPCB Application Manual

Auxiliary Switch (Field installable kit available)
The auxiliary switch is used for indication of breaker main
contact position. It is available on manually and electrically
breaker primary contact position while normally closed
(NC) contacts operate opposite the breaker primary con-
tacts. All auxiliary switch contacts feature rugged double-
break construction. Refer to breaker wiring diagram
10057403P1 for contact configurations and secondary dis-
connect terminations. Ratings of the auxiliary switch con-
tacts are shown in Table 7.1.

Bell Alarm with/without Lockout (Field installable kit available)
The bell alarm device is provided with two C-form contacts
— each C-form contact is
1NO and 1NC contact with
a common connection. The
bell alarm device operates
whenever the breaker trips
due to a protective function
of the trip unit. It can be
used to provide remote indi-
operated breakers in either
a 4-stage or 7-stage config-
uration. The 4-stage switch
yields 3NO and 3NC con-
tacts while the 7-stage
switch yields 6NO and 6NC
contacts. Normally open
(NO) contacts follow the

cation of a fault trip and/or disable electrical operation of
breakers that may have automatic control.
For Power+™ and MicroVersaTrip Plus™ trip units, the bell
alarm will operate for overload, short circuit and ground
fault trips. For MicroVersaTrip PM™ trip units, the bell
alarm will operate for the same overcurrent trips plus any
of the protective relay trips that are enabled in the trip unit.
Tripping via the manual trip button, shunt trip, undervoltage
device or open fuse lockout will not operate the bell alarm.
The bell alarm can be furnished with a mechanical lockout
feature that will prevent the breaker from being manually
closed until the lockout is reset. Reset of the contacts and lock-
out feature is accomplished by pushing the yellow "reset" but-
ton on the breaker escutcheon. The reset button also serves as
a target indicator that the bell alarm has been operated.
Ratings of the bell alarm contacts are shown in Table 7.4.

Electrical Lockout (Field installable kit available)
The electrical lockout device provides a means to electrically
enable or disable manual closing of a circuit breaker. This
device must be energized prior to attempting to manually
close the breaker. Once the breaker is closed, loss of voltage
will not trip the breaker. A manual bypass interlock is pro-
vided for initial startup. Refer to the undervoltage device for
ratings and coil characteristics. (Note: Interlocking of elec-
trically operated breakers does not require an electrical
lockout device.)
