Abstract: An electrical connection device for an electrical apparatus includes a connection pad and two attachment flanges arranged on either side of the connection pad. The attachment flanges and the connection pad include opposing cavities for delimiting four recesses capable of receiving at most four conductors. A pass-through clamping mechanism, formed by two lateral tie rods and a central rod, passes through the assembly constituted by superposition of the attachment flanges and the connection pad. The lateral tie rods include a support abutment arranged between the connection pad and one of the attachment flanges so that it is possible to differentiate the tightening, recess by recess, facilitating the placing of the conductors, the conductors being able to have different diameters.

Abstract: A trippable control system for one or more electrical breaker poles includes a first link pivotable about a first pivot point between first and second positions; a second link pivotable about a pivot axis for connecting to one or more breaker poles, whereby movement of the first link causes the second link to pivot about the pivot axis between a position for opening and a position for closing the breaker pole(s); and a trip mechanism suitable for releasing the first pivot point and for exerting a movement force on the first link to move the first link between the second and third positions when the first link pivots about a second pivot point. Movement of the first link between the second and third positions causes the second link to pivot about the pivot axis between the position for closing the breaker pole(s) and the position for opening the breaker gear.
