When the circuit is switched on, the control circuit provides driving current for the switching-on and switching-off coils, the directions of the magnetic fields generated by the coil current and the magnetic fields generated by the permanent magnets are consistent and are mutually superposed, so that the driving force of the operating mechanism is greater than the switching-off holding force of the circuit breaker, the moving iron core starts to move to reduce the magnetic gap, the driving force of the operating mechanism is sharply increased along with the reduction of the magnetic gap, and finally the moving iron core is pushed to the switching-on position. Because the closing ferromagnetic loop is closed, the magnetic field force of the permanent magnet is enough to meet the requirement of maintaining the closing of the circuit breaker, so that the circuit breaker is kept in a closing state, and the control circuit cuts off the coil power supply according to the protection time set by a program after the circuit breaker is closed.
