Title: BREAKER
Abstract:
The present invention addresses the problem of improving the operability of a breaker. This breaker is provided with: a breaker main circuit (31); a breaker main circuit conveying unit (20); a fixed side locking member (25); a front side unit (26); and a switchboard (90). A lock releasing member (24) is attached to the front side unit (26) or the fixed side locking member (25). When the breaker main circuit conveying unit (20) is placed at a first position, a moving side locking member (23) is at an initial position. When the breaker main circuit conveying unit (20) moves backward from the first position, the moving side locking member (23) moves toward a retraction position interlockingly with the lock releasing member (24). When the breaker main circuit conveying unit (20) reaches a second position located further back from the first position, the moving side locking member (23) returns from the retraction position to the initial position, and is engaged with an engaging hole (25a) bored in the fixed side locking member (25).
