Magnetic circuit breaker is a circuit breaker that works by electromagnetic principle. It determines whether the circuit is overloaded through the magnetic force generated by current induction, and quickly cuts off the circuit when overload or short circuit is detected to prevent equipment damage or circuit fire.
