Contactor-circuit breaker housing firstly power poles and an electromagnet serving to activate the moving contacts in contactor mode and including a fixed magnetic circuit, a moving magnetic circuit and a coil whose electric supply is controlled by a switch, and secondly at least one current sensor serving to control a releasing electromagnet. The activating electromagnet and the releasing electromagnet are constituted by a single electromagnet whose moving magnetic circuit is a pivoting pallet linked mechanically to the contact-holders of the poles and having a weak moment of inertia. An electric unit is provided for the rapid reduction of the magnetic flux, triggered by an electronic control device associated with the current sensor.
A contactor-circuit breaker housing power poles which include a moving contact bridge cooperating with fixed contacts and an electromagnet activating the moving contact bridge in a contactor mode and including a fixed magnetic circuit, a moving magnetic circuit which is pivotally pallet engaged mechanically to said moving contact bridge, a coil whose electric supply is controlled by a first switch, and at least one current sensor to control a releasing electromagnet, wherein the activating electromagnet and the releasing electromagnet are constituted by a single electromagnet, said contractor-circuit breaker comprising:
