7.2 Main connection types for fixed mounting
Rear flat busbar terminals
Rear flat busbar terminals are used to adapt VL630 to VL1600 molded case circuit breakers
to switchboards or other applications that require rear connection. The rear busbars are
bolted direct to a standard 3VL molded case circuit breaker without requiring any
modification. A vertical or horizontal connection is established, depending on the way the
busbar terminals are mounted to the rear of the circuit breaker. Molded case circuit breakers
mounted in switchboards or other electrical equipment with the help of rear flat busbar
terminals may be removed from the front by removing the fixing screw that connects the
molded case circuit breaker to the terminal.
