The device includes two breaking areas formed at each side of a contact bridge carrying main contacts that can be separated from fixed contacts located in the breaking areas and fixed to main conductors. The main conductors each have shaped extensions in the break areas that are configured to cooperate with shaped extensions associated with arc collection parts positioned nearby. The shaping of the extensions and the spacing therebetween encourage a particular direction of arc migration relative to arcs created when the moveable contacts carried by the contact bridge are separated from the fixed contacts. Further, arc migration control is provided in the form of magnetic fields provided in each breaking area. Each arc collection part is connected through a shunt conductor and a single direction of current flow establishing component to make a direct electrical connection to the main conductor associated with the other area.

A reversing contactor apparatus in a single case is disclosed, comprising electro-mechanical locking means. These means which comprise a mobile mechanical locking piece, further having surfaces for actuating locking switches, are placed substantially in the plane of a median dividing wall, on each side of which each of the two contactors of the apparatus are disposed; these conductors connect these switches in series to each contactor coil and, respectively, to a connection terminal.

Motor speed controller

A variable composition switching device realizable by the assembling of modular elements and including at least one circuit breaker module i.e. switch module and at least one control and/or protection module. The circuit breaker module consists of a case with two opposing junction sides allowing for assembly by juxtaposition of several circuit breaker modules, one assembly side comprising a duct orifice of the thruster of the curcuit breaker device and two assembly areas of a control and/or protection module. The control modules include suitable means for activating the thruster.

A variable composition switching device which comprises one basic modular component incorporating at least one controllable switching device, one direct switching control modular component and/or one indirect switching control modular component. This indirect switching control component acts on the basic modular component through a potential energy accumulation tripping device.
