Abstract

A circuit breaker is provided. The circuit breaker includes housing, a frame that is fixed to the housing, and a make and break mechanism. The housing is configured to comprise a double-break unit case having two pairs of the moving contact point and the stationary contact point or a member that is different from the double -break unit case. The frame has a first fixing portion for fixing the make and break mechanism to the double-break unit case and a second fixing portion for fixing the make and break mechanism to the housing in which the member is provided
