PROBLEM TO BE SOLVED: To provide a circuit breaker for wiring that enables turning-on/off of an alarm switch without allowing any shock resulting from a movement of a link mechanism to be transferred to the alarm switch as-is. SOLUTION: An alarm cam 1 for turning on/off the alarm switch 2 disposed inside the circuit breaker for wiring is adapted to operate via a connection spring 1a and a latch 41 of the link mechanism 4 that brings a breaking mechanism section 3 into an on, off or trip state. As a result, the alarm switch 2 is turned on/off by the alarm cam 1 in which a shock from the link mechanism 4 when brought into the on, off or trip state is reduced by the connection spring 1a, so that the alarm switch 2 will not suffer damage.
