Claims

[Scope of utility model registration request]

A latch for the opening/closing mechanism and a latch receiver for locking the opening/closing mechanism are supported on a frame having side plates on both sides of the movable contact of the central pole, and a rotatable trip cross that straddles each pole is mounted on the back of the latch receiver. In a circuit breaker that engages with bar claws, a U-shaped mounting bracket with arms on the left and right is fixed to the trip crossbar,
A trip circuit breaker characterized in that a claw is formed on one of the arms, and the trip crossbar is rotatably supported on a side plate of the frame via pins inserted through the left and right arms. Crossbar.
