NTERLOCKS

:

 

The AMVAC™ circuit breaker contains a number of interlocks.  A description of each interlock follows as encountered 
during racking of the circuit breaker into the compartment.

NTERLOCKS

:

 

 The position release lever must be depressed in order to begin racking the circuit 

breaker in any direction from any positive position (Disconnect, Test, or Connect).  The release lever is blocked from 
actuation when the circuit breaker is CLOSED.  The ability to close the circuit breaker is blocked mechanically and elec-
trically unless it is in one of the three positive positions.  If the circuit breaker is in  between positions, the remote close 
signal and front panel close signal are disengaged and the circuit breaker cannot be closed.

PERATION

: 

(Opening)

 

(Refer to Table 2, Appendix A, and Fig. 8) 

The circuit breaker can be operated manually  (opening only) or electrically.  The manual Opening Handle is required for 
manual operation. 
1.  Inspect the initial state of the circuit breaker to determine the operations available (Refer to Table 1 and Fig. 2) 

a.  Close/Open indicator (6) 
b.  Stored Energy Charged/Discharged “Ready” Indicator (2) 

2.  Manual opening may be performed in any position, but should be avoided when the circuit breaker is in the Connect 
     position.  Any manual operation while the circuit breaker is racked onto live bus should be avoided to insure added   
     safety to the operator.

LOCKING

:

   

A interference blocking plate (Fig. 1) in the circuit breaker compartment prevents 

under rated circuit breakers from being inserted into higher rated compartments.  The code plate rating includes 
continuous current, interrupting current, close and latch capability, and maximum voltage.

extended into the compartment slots.

EMOVAL

:

  The handle release pin prevents withdrawing the circuit breaker from the 

compartment by blocking withdrawal of the locking tabs.  The handle release pin blocks the handles unless the circuit 
breaker is in the Disconnect position. 

OPERATION, INSTALLATION, AND MAINTENANCE

 

DANGER 

 

Inside the breaker there are stored energy capacitors that must be discharged prior to removing the 
front cover of the breaker.  Wait 20 minutes after breaker removal from the cell prior to removing the 
front cover of the breaker for the discharging of the storage capacitors to occur. 

DANGER 

 

MODIFICATION TO INTERLOCKS CAN RESULT IN HAZARDOUS 
CONDITIONS TO PERSONNEL AND EQUIPMENT.  DO NOT OVERRIDE, BY-
PASS OR ADJUST INTERLOCKS.
