SECONDARY DISCONNECTOR OF DRAWER CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To provide a secondary disconnector of a drawer circuit breaker capable of constituting a small drawer circuit breaker in a simple configuration. SOLUTION: There are provided a frame-side connector 10 which is slidably provided on a drawer frame 1 and comprises a frame-side contact member 6, a connector resetting spring 17 that energizes the frame-side connector 10 leftwise, a lock lever 14, and a slide pin 20 provided to a frame-side connector fitting plate 18. A body-side connector 24 comprising a body-side side contact member 8 is provided on a breaker boy 2, and a lock lever receiver 23 is formed at a fitting plate 22. The body-side contact member 8 contacts the frame-side contact member 6 on the way of the breaker body 2 moving from a disconnection position to a test position. So the lock lever 14 is energized clockwise and its rotation is blocked by the lock lever receiver 23, with the frame-side connector 10 remaining at the position. On the way to a connection position, engagement with the lock lever receiver 23 is released, and the frame-side connector 10 moves together with the body-side connector 24.
