Abstract: An automation device includes a modular assembly with a primary group configured for use with a hardware element. The primary group includes a controller providing signals. A feeder unit provides power to automated units. A primary first link connects the input/output modules, the primary first link carrying the signals and carrying power to the input/output modules. A primary second link connects the input/output modules and carries power to the automated units. A terminating module connects to the primary first and second links. A secondary module group is associated with a secondary zone of the hardware element. The secondary group includes a lead module connected to a secondary first link and a secondary second link, the secondary first link connected to the primary first link. A cable connects the terminating module with the lead module.

Abstract: An electrical apparatus including a base configured to be fitted to a holding rail with opposing coplanar arms, and configured to accommodate a component member of the apparatus and fitted with a locking device having two opposing catches each intended to hook onto a respective arm of the rail. Further, at least one of the two catches is joined to a slide configured to slide in a direction and can be moved by a manual unlocking member. In addition, he manual unlocking member includes a lever pivoted around at least one bearing pin having an axis perpendicular to the sliding direction of the slide, and the lever cooperates with the slide bar via a cam device guiding through a slide track having an axis parallel to the axis of the bearing pin.

Abstract: An automation device comprising a modular assembly associated with a hardware element. This assembly includes in the primary group of modules a bus coupler 20, a feeder unit 21 to distribute feeder power at voltages Uin, Uout for the automated units, functional modules 22 and a terminating module 30.

Abstract: Electrical apparatus comprising a base which can accommodate a constituent member, and which can be fitted to a holding rail, in particular a top hat-type rail, via a locking device with two opposite fastening catches (30), one of which is joined to a slide (31).

Abstract: An assembly of electrical equipment having devices, such as circuit breakers and contactors grouped in pairs, included on a supporting baseplate. Each pair of devices includes a circuit breaker 40 and a contactor 60 and a baseplate 20 having power pins and control pins that cooperate with respective power and control terminals of the devices. Auxiliary units 50,70 are fixed to one of the devices 40,60 while being connected to control terminals 45,65,66 of the one device. The units 50,70 are connected to a linkage with a bus or a control and command system by plugging units 50,70 into control pins 81,82 of the baseplate 20.

Abstract: An electronic variable speed drive including a cabinet having an opening door, a power system supplied with power from an AC line voltage and delivering a voltage under the control of solid state power switches and an electronic control system controlling the solid state switches. The cabinet contains, behind the door, a protective cover which protects the electronic control system and the power system which are disposed behind it. When the door is open, the protective cover protects users from the control and power systems.

Abstract: A device for manually controlling a thermal relay associated with a contactor and housed, together with the contactor, in a case having stop and reset push-buttons, comprises levers mounted for rotation in a support fixed to the front of the box of the thermal relay. Each of the push-buttons engages a respective lever so that the latter is applied on a stop pusher or a reset pusher of the thermal relay. A combined stop and reset operation from the actuation of the stop push button alone is possible because the stop lever bears on the reset lever.

Abstract: A device is disclosed for the manual control of thermal relays, comprising a case with a push-button on a front wall and having a transmission member; the latter comprises a rigid support and a resilient lever applicable on the stop and re-set pushers of a thermal relay. A drive element proper to the push-button is applicable on an intermediate zone of the resilient lever.
