ABSTRACT:
Linked circuit breakers linked with an interlocking lever having hollows respectively receiving each handle of each circuit breaker and having a groove to be fitted in by the connecting pin positioned between each handle are fixed side-by-side. The groove of the interlocking lever has protrusions which make the groove narrower than the diameter of the connecting pin to fix the connecting pin. Thus, the interlocking lever is mounted easily to the handles of the circuit breakers by the connecting pin which inserts through the through holes of the handles.
