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: This invention relates to a multi-pole contactor—circuit breaker type switch composed of a housing (1) containing breaking poles (11) activated by a control electromagnet (16) and by a trip control mechanism (18, 14) and comprising a protection module (2) equipped with means (21) for measuring pole currents and means (22) for acting on the electromagnet (16) and on the trip control mechanism (14) if a fault current is detected, characterised by the fact that it comprises a control and/or communication module (3) that is installed removably on the housing, below the protection module (2) and communicating with the processing circuit (22) on the said protection module (2) through connectors (23, 33).

Abstract: An add-on unit for coupling to a main electrical appliance with separable power contacts, including a housing having a front face and a rear face, and for mounting frontally against or into such main appliance, wherein the front face includes first connections having an input-output function for connection with communication conductors for communicating with a device for control and monitoring of such main appliance, and second connections having an output function for connection with communication conductors for communicating with command input terminals of such main appliance, wherein the first connections are pins located in a connector on the front of the housing, the first connections comprising signal input connections to command such main appliance and signal output connections for signalling a status of such main appliance.

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.
