The present invention relates to a power supply control module for loads or motors, which is mounted as an addition under a main electromagnetic switch appliance (Ap) and having, in a casing ( ), current paths with commutating poles controlled by an electromagnet control device and substantially characterized by the fact that it includes at the rear, means ( ) capable of channelling gases flowing out of the breaker chambers of the main appliance (Ap).

Module combined with an electromagnetic switch appliance

The present invention relates to a multipolar electromagnetic switching module designed to be connected by line connections (t , t , t ) to a main electromagnetic switching device (AP) and by load connections (U, V, W, u, v, w) to at least one motor and having, in a unit (Bo), between said connections, several load paths fitted with switching poles whose contacts are always alternately closed and controlled by a switching electromagnet (EI) driven by a control circuit, each of the switching poles (C , C , C ) consisting of a movable contact holder (Pc) between two conductors (Cf , Cf ) bearing fixed contacts characterized in that, for each pole, the movable contact holder (Pc) comprises two parallel loop-shaped conductors (Cm , Cm ) connected to a connection (T , T , T ) and that the two fixed contact parts (Cf , Cf ) are loop-shaped and connected to connections (U, V, W).

Multipolar electromagnetic switching module

The present invention relates to a multipolar electromagnetic switching module that is connected by line connections (t,t,t,) to a main multipolar electromagnetic switching device (AP) and by load connections (U, V, We U&prime;, V&prime;, W&prime;) to at least one motor and having between said connections several power current lines (C,C,C,) fitted with switching poles the contacts of which are always alternately closed, and controlled by a switching electromagnet (E,) driven by an electric control circuit (CC), and characterized in that the switching poles (C,C,C,) and current lines are arranged to perform a motor control function such as reverser, star-triangle or distributor and in that the pole control assembly consisting of the switching electromagnet (E,) and the control circuit (Cc) is offset relative to the switching poles and load paths in a direction perpendicular to the rear fastening surface (P) of the module such that the width (L) of the module is reduced and more or less identical to that of the main device (AP) associated with it.

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

An electronic relay including current sensors (11, 12, 13) mounted, between terminals (L1, T1, L2, T2, L31, T3), in series on alternating current power supply lines to a load (M). A back of a case (1) of the electronic relay includes a power card (C1) linked to the current sensors (11, 12, 13) and connected via connectors to electronic daughter cards (C2, C3, C4) carrying lateral terminal blocks (B1 and B2) which have outputs in the lateral openings of the case. A front of the case (1) includes a dialogue and communication card (C5) connected to at least one of the daughter cards (C3).

Electronic relay

An electronic relay having a current sensor device (C1, C2, C3), logic inputs (3) and an electronic circuit (4) provided with processing means capable of calculating, from the current signal (I) supplied by the current sensor device and a rectified voltage signal (V) supplied by one of the logic inputs, the value of the power factor of the motor (cos.phi.) and/or the value of the power supply voltage (U) of the motor.
