Abstract

A circuit breaker has a molded case 1 including a stationary contactor 3 having a stationary contact, a movable contactor 4 having a movable contact, a U-shaped slitted arc-extinguishing chamber 5 surrounding the stationary contact and the movable contact, a trip crossbar 10 actuated by an overcurrent tripping device 8 in action, and a latch catcher 11 facing the trip crossbar and normally made engaged with a latch 7 to hold the latch in a locked position. The latch catcher is disposed with downward extension between the arc-extinguishing chamber and the trip crossbar. The molded case 1 further has a gas flowing out path defined as a space between the arc-extinguishing chamber and a gas outlet 1c on the side of a load side terminal 2, in which the latch catcher is positioned. Moreover, a metal protection cover 13 of a thin steel sheet, covering an engaging section with the trip crossbar for providing a shield against molten metals scattered around from the arc-extinguishing chamber, is secured onto the back of the latch catcher by making their fastening parts engaged with each other with one of the fastening parts made deformed.
