An electromagnetic device of a switching apparatus including a mobile armature for rotating in a fixed frame between two inactive and active positions, at least one permanent magnet mounted in the fixed frame, and at least one coil mounted in the mobile armature and control means for delivering a control current into the coil. The mobile armature is monostable; in an inactive position, a lever actuated by the mobile armature separates the fixed contacts from the mobile contacts of the apparatus. In an active position, the lever is released from the mobile armature and a spring presses the mobile contact against the fixed contacts.

Rotary electromagnet

A module including at least two electrical components such as thyristors including a temperature sensor soldered on two conducting strips on a flat cable formed by a flexible dielectric plastic film glued onto the metallic electrode forming the top of one of the components and approximately at its center.

Electronic power components module

Control device for a multiphase electric motor (M) comprising firstly two two-directional static switches (IS1, IS2) each associated with a terminal of a shunt contactor (S) installed in parallel, these switches (IS1, IS2, S) being controlled by a control circuit (C) controlling progressive operation of the motor, characterized in that the shunt contactor (S) is of the four-pole type and is fitted with solid connection parts (6, 7) each connecting two terminals of the said contactor, these connection parts (6, 7) being connected in pairs (L1, L3) to the terminals of the static switches (IS1, IS2) such that each (IS1 or IS2) is connected to two terminals.

Control device for a multiphase electric motor

A circuit for the protected alternating current power supply of an electrical load, the circuit including, in series, a protective circuit breaker and a bi-directional electronic switch in parallel to which a shunt contactor is connected. An electrical component is connected in series and upstream from the shunt contactor. The electrical component is intended to establish a continuous voltage (V) at the terminals of the electronic switch and its impedance is chosen in such a way that the electronic switch to which command pulses are sent periodically, is made a conductor, when an overload current appears in the circuit and when the contactor is closed.

Circuit for the protected power supply of an electrical load

Power supply circuit for a single-winding electromagnet coil (11) comprising a low voltage DC power supply (20) and a high voltage AC power supply (30) both connected to the terminals of the winding (11), together with a switching apparatus (40) connected in series with the high voltage supply (30) and capable of supplying or cutting the high voltage power supply to the winding (11), characterized by the fact that the switching device (40) comprises a thyristor (42) connected between the high voltage source (30) and the winding (11) and a control circuit (43) for the thyristor (42) connected to the gate (G) of the thyristor used to cause the thyristor to conduct when the high voltage source (30) delivers the positive phase of a voltage wave.

Power supply circuit for an electromagnetic coil having low DC and high

An electrical device for switching an arc to a path parallel to a device to be protected. The electrical device includes double breaking contacts and an arc transfer electrode associated with the parallel path. The parallel path shunts the double breaking contacts and a device to be protected via the arc transfer electrode. The arc transfer electrode is placed in the vicinity of a fixed contact of the double breaking contacts.
