An electromechanical circuit breaker for establishing and breaking the current in a main circuit includes a fixed contact element and a moving contact element, which in a first position are in electrical contact with each other for carrying the current of the main circuit, the moving contact element being adapted to be displaced to a second position in which it is separated from the fixed contact element so that the current in the main circuit is cut off. The circuit breaker is provided with a blow-out device including a magnetizing coil traversed by a magnetizing current for producing a magnetic field adapted to drive an arc generated by the separation of the two contact elements into an arc extinction element.

Electromechanical circuit breaker

A release mechanism for a circuit interrupting device includes a ferromagnetic main frame through which can flow a current and a ferromagnetic movable core designed to be translated in an opening of the main frame between a first position where the circuit interrupting device remains closed and a second position where the circuit interrupting device is opened. The release mechanism is designed to use the flux generated inside the main frame by the current flowing through it to displace the movable core between its first and second positions. The release mechanism further includes at least two permanent magnets mounted on the main frame on each side of the opening and relatively oriented so as to generate a unidirectional unique magnet flux inside the main frame and the movable core, the magnet flux creating a first force on the movable core that tends to maintain it in its first position.
