Abstract (en)
[origin: EP0246727A2] A circuit breaker equipped with a key-operated lock 11 has a movable element 20 on which is secured a moving contact 20a. The movable element 20 is directly pivoted on a crossbar 21 by a pin 22. The crossbar 21 is made of a molded thermosetting resin and has an engaging portion 21c in the form of a protruding arm integrally formed thereon. The engaging portion 21c engages with a movable portion 11c of a lock 11. The engagement between the engaging portion 21c of the crossbar 21 and the movable portion 11c of the lock prevents the movement of the crossbar 21 and locks the circuit breaker.
