The construction of the circuit breaker is compact and can be miniaturized easily. It mainly consists of solenoids, contact latches with a permanent magnetic core, and a bistable structure.With creative design of the contact latches, the breaker permits brief current surges beyond normal running current.By altering the design parameters of the solenoid or bistable structure or contact latch, an array of circuit breakers are available to detect a variety of current thresholds. The circuitbreaker can be reset automatically and immediately to restore power without delay.Ambient temperature does not affect the current threshold of the magnetic breakerand require no cooling period after a power surge or short circuit.
