Abstract
A control device for an electromechanical circuit breaker device. The device includes a bistable type electromagnet to deliberately control power contacts and a monostable trip electromagnet to open the contacts in case of a fault. The bistable electromagnetic coil and the trip electromagnetic coil are placed in parallel with a capacitance. The control device includes a maintained control switch and an H bridge of two-way switches associated with the bistable coil. The control device acts on the bridge of switches and a trip switch opens the contacts depending on the current in the coils measured by sensors.
