Front connecting bars for increased pole spacing are used to establish busbar connections
in switchboards or other electrical equipment. Normal use enables adjustment to the next

For additional information, refer to the technical data in the chapter Configuration of main
connections (Page 136).
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
breakers mounted in switchboards or other electrical equipment may be removed from the
front by removing the fixing screw that connects the molded case circuit breaker to the
terminal.
