Abstract: A motor starter device having an elongated base provided with power poles acted upon by a contactor part and a protection part. The base houses power current lines 15 and their control mechanism 20. Two movable linkages (30, 40) are associated with the mechanism, namely a first linkage 30 controlled by the electromagnet in the contactor part 16 and a second linkage 40 moved by the tripping device 18 in the protection part or by the manual control button 17. The linkages actuate signaling contacts 31, 32, 41, 42, 43 44 staggered on different levels, these contacts being housed in removable blocks A, B, added onto the housing in a fixed part C subjacent to the housing.

Abstract: Motor starter device comprising an elongated base provided with power poles acted upon by a contactor part and a protection part.

Abstract: The housing of the add-on unit presents on the front, on its face 31a, input-output connections 33 suitable for the connection of communication conductors, particularly to a bus cable, to assure linkage of the appliance with a command and monitoring device. It also comprises connections 35 with an output function which enable the connection of conductors for linkage with the command input terminals of the equipment.

Abstract: The present invention relates to an apparatus for motor protection and control containing power conductors provided with poles with separable contacts (Ct) and a protection device (Mp) containing means (Cc) for detecting currents flowing through the power conductors and means for generating an initiating signal in order to control an electromagnet (Ea) and a mechanical device (Sm) with trip mechanism (Dr) which is able to actuate moving contacts (Cs) and a connecting strip (T2) and which can be actuated by a manual control button (Cm), characterised by the fact that the mechanical device (Sm) has means for automatically resetting the trip mechanism (Dr) after it has tripped and for moving it to the off position.

Abstract: The device comprises a sink (12) and a clamping devicew (17, 18) associated to each semiconductor component (15, 16) for applying the latter to the sink (12). The clamping device bears on one hand on the sink (12) and on the other hand on the semi-conductor (15, 16) through a laminated connection bar (20) to present, length-wise and from a clamping range (23) on a fixed support (10), a flexibility enabling the bar (20) to be applied to bearing ranges of semi-conductor components having different heights. The device may be used for variable height power semi-conductors.
