Abstract
A circuit breaker is formed of a stationary contact member bent back into a U-shape and having a stationary contact at a bent back portion thereof, a moving contact member situated adjacent to the stationary contact member to be able to contact with the stationary contact, a plurality of grids laminated vertically with a space therebetween, and a unitary molded insulator situated around the stationary contact member. The insulator includes a pair of side walls facing to each other, and a plurality of slots arranged in the opposed side walls to vertically space apart from each other. The grids are inserted into the slots to be vertically piled when the circuit breaker is assembled. The circuit breaker can be easily assembled.
