Abstract
A molded case circuit breaker interlock unit connects between a fuse enclosure attached to one end. Upon the occurrence of a short circuit within a protected circuit, the fuse operates to isolate the protected equipment and is conveniently replaced without disassembling the circuit breaker components. The interlock unit prevents resetting the circuit breaker operating mechanism until the fuse is replaced.
