Source Changeover Interlocks
•
Source changeover interlocks allow mechanical interlocking between two or three circuit breakers
(fixed and drawout).
NOTE: Source changeover interlocks for Masterpact NT circuit breakers are IEC only.
Open Door Racking Interlock (VPOC)
The racking interlock prevents racking in the circuit breaker when the door is
open. (Insertion of the circuit breaker racking handle is not possible when the
compartment door is open.)
Automatic Spring Discharge Mechanism (DAE)
The automatic spring discharge mechanism is standard for UL and ANSI
circuit breakers, and optional for IEC circuit breakers. It releases the closing
spring energy when the circuit breaker is moved from the disconnected
position to the fully withdrawn position. Not available for IEC Rated
Masterpact NT circuit breakers.
Cradle Rejection Kits
The cradle rejection feature (standard) ensures that only the properly designated circuit breaker or
switch is matched with the selected cradle assembly.
Rail Padlocking
Rail padlocking is standard for UL, ANSI, and IEC cradles. When used in combination with the
disconnected position locking device, rail padlocking prevents the movement of the circuit breaker from
the disconnected position to the fully withdrawn position when the padlock hasp is pulled out and locked.
