Contactor-circuit breaker comprising a control electromagnet and a protection device both capable of acting on mobile contacts in response respectively to a deliberate control and to a detected electrical fault, through a multi-pole device. An electromagnetic tripping device () is added onto a contact control mechanism (). The protection device (), preferably interchangeable, is connected to the electromagnet () through a control line (B) and to the control mechanism () through a trip line (A) so that it outputs an electrical power supply to the electromagnet on the control line, and in the case of a fault, a trip signal on the trip line. The electromagnet () is of the DC type, and the protection device () adapts its power supply voltage.

Reverse current relay

Inductive current sensor and electrical apparatus incorporating this sensor. The magnetic circuit of the sensor comprises a separable part carrying the detector element and is made of a material having a permeability lying between 5 and 100. The circuit reduces the influence of spurious gaps and external interference on the current sensor for the electrical apparatus.

Inductive current sensor with reduced influence of spurious gaps and

A switch having at least one power switching pole includes a contact bridge cooperating with fixed contacts and adapted to be maneuvered either by mobile parts of a solenoid or by a tripping mechanism. The contact bridge is rotatable and the mobile parts of the solenoid operate the contact bridge through the intermediary of a transmission mechanism.
