    摘要: Control circuit for electromagnet with two coils used to determine a call phase and a hold phase, and powered from a DC power source. The energy source comprises a current generator and a capacitor powered by this current generator. A control device controls two switches, in which the first switch controls discharge of the capacitor in the first coil during the call phase, and the second switch sets up current passing through a second coil during the call phase and the hold phase. The required current output from the current generator is thus reduced.

    摘要: 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.

    摘要: A magnetic trip with a fixed magnetic circuit polarised by a permanent magnet. The magnetic circuit includes two preferably identical parallel wafers each defining a main branch and a deflection tab with the presence of a coil on each branch. At their ends opposite to the mobile pallet, the wafers have in cross-section an L shape. The insulation structure carrying the coils is formed of two half-shells tightly holding the wafers. The trip can be used in circuit breakers.
