Abstract: An installation for the electrical connection between an assembly of items of electrical equipment which are affixed onto a common baseplate and a system for command and control of that assembly. The installation includes an electrical interface device which provides a connection of signals from the equipment in the assembly with the signal linkage connected to the system. The interface device can be mechanically dissociated from the base plate and is attached to it by a detachable fixing element. The device includes a casing which houses a printed circuit by which two connectors are located which respectively provide the electrical connection with the assembly and with the linkage and which are interconnected through a printed circuit. One of the connectors is specifically adapted to the type of linkage used.

Abstract: A motor starter assembly made up of sub-assemblies each formed from a circuit breaker 40 and a contactor 60 and positioned on a baseplate 20 with which a set of power bars 23 is associated. The baseplate includes a support area 21 for the sub-assemblies and a connection are preferably a bracket 22 that is overhanging in relation to the support area. The baseplate further includes power connection elements and or control connection elements provided on the bracket and the connection area to permit plugging in of the sub-assemblies on the baseplate along an engagement direction Z approximately parallel with the support area and perpendicular to a direction X of a set of bars.
