Rear terminals
Rear terminals are used to adapt the 3VL molded case circuit breakers to switchboards or
other applications that require rear connection. They are bolted direct to a standard
3VL molded case circuit breaker without requiring any modification. Molded case circuit

front by removing the fixing screw that connects the molded case circuit breaker to the
terminal.
