CIRCUIT BREAKER AND HANDLE LOCKING DEVICE THEREOF

摘要

Disclosed is a handle locking device, including a first frame, a first snap hook and a second frame. A second snap hook is provided on the first frame; the first snap hook is rotatably mounted on the first frame; the second frame is rotatably mounted on the first frame; a protruding portion is formed on the second frame; and the protruding portion can push the first snap hook towards the first frame. By having the first snap hook and second snap hook disposed asymmetrically on the first frame, accidental mounting of the “OFF” position of the handle locking device in the “ON” position of the circuit breaker during installation by an operator can be avoided. Moreover, since the protruding portion can push the first snap hook towards the first frame, forced deformation of the snap claw and second snap hook can be prevented.
