PURPOSE: To improve attachment installation workability by disposing each actuator of an attachment above a cross bar by enabling the attachment to be assembled easily from above.
CONSTITUTION: When an attachment 16 is inserted in a recessed place 15 from above, each of actuators 27, 29 is protruded from an actuator insertion hole 18 into a breaker case 1A to be positioned above a cross bar. An auxiliary switch 25 of the attachment 16 is changed by the actuator 29 kept without being engaged with the cross bar when a breaker is on, and the actuator 29 engaged with the cross bar when the breaker is off, and on/off display is made. By thus assembling the attachment 16 from above the attachment 16 can be assembled in the case 1A easily, and it can be installed easily at a customer's site, thereby attachment installation workability can be improved.
