Claims

[Scope of utility model registration request]

An electromagnetic block that opens and closes contacts through handle operation and a link mechanism, a detection mechanism that detects abnormal currents such as overcurrent and short circuit current, and an output from the detection mechanism that releases the latch engagement and drives the link mechanism. It has a trip mechanism that forcibly opens the contacts, a roughly U-shaped frame that supports the link mechanism and trip mechanism members between both side plates via a shaft, and an electromagnetic block that supplies power to the electromagnetic block in conjunction with the operation of the handle. In a breaker equipped with a first limit switch to be supplied and a second limit switch to output an alarm to the outside when tripping is performed, both limit switches are fitted to form a substantially U-shaped switch fitting made of an insulating material, A breaker characterized in that both side plates of the switch fixture sandwich both side plates of the frame, and the side plates of the switch fixture are positioned outside both ends of the shaft.
