Claims

[Scope of utility model registration request]

It has a mechanism that detects the fault current flowing in the main circuit and automatically cuts it off, and an operation display that shows what kind of accident caused the automatic cutoff.The permanent magnet normally attracts the movable iron piece, but in the event of an accident, the movable iron piece is pulled away. In a breaker having a release spring and a latching solenoid consisting of a coil for applying a magnetic field in the opposite direction to the magnetic field of a permanent magnet, the latching solenoid has an attractive force of 150 to 350 grams without the release spring. The coil has a characteristic that the input power is 50 to 200 milliwatts, is attached to a frame made of a magnetic material, connects the movable core and a link equipped with a display button with a pin, and operates in conjunction with a latching solenoid. The direction of the force of the leaf spring for operating the microswitch is perpendicular to the direction of movement of the pin, and when the operation display device is reset, the direction of the force of the leaf spring acting on the pin is in the direction of movement of the pin. 0° to
A circuit breaker operation display device characterized in that the angle is 30°.
