Abstract: A system has an electronics housing and a grounding contact assembly for electromechanical switchgear that can be mounted on a mounting rail, wherein the grounding contact assembly can be mounted in the electronics housing. The base region of the electronics housing faces a mounting rail, is provided with an externally accessible mounting duct for a grounding contact that can be mounted in the duct, and contacts the mounting rail in a spring-leaded manner. The contact part has a blade contact at one end and at the other end a terminal receiving part which is angled perpendicularly to the first free end of the blade contact and is designed as a detent pin. The grounding contact assembly can be pushed into the mounting duct irrespective of the position of the electronics housing on the mounting rail.

Abstract: An interlockable lock-out handle system for an electrical switching device includes a lock-out rim and a lock-out handle. The lock-out rim is configured to be disposed over an operating shaft of the switching device and fastened to at least one of switch housing and a front plate. The lock-out handle is configured to be fastened by a clamping device in rotational engagement on the operating shaft. The lock-out handle includes a rotary handle having a grippable lateral surface and a lock-out collar. The lock-out collar is vertically displaceable relative to the rotary handle in a direction of a longitudinal axis of the operating shaft into a CLOSED position and an OPEN position. The lock-out collar is engaged with the lock-out rim so as to prevent twisting movement of the lock-out collar relative to the lock-out rim when the lock-out collar is in the CLOSED position.

Abstract: A multi-phase cross connection link for carrying potential between at least two switching devices modularly connected on a support member, each switching device having connector holders for accepting the potential, includes a conductor rail associated with each phase and disposed in a housing, the housing being made of insulation material and extending in a lengthwise direction. A plurality of tabs is associated with the conductor rail, the tabs extending outward in a comb-like manner in a shared plane perpendicular to the lengthwise direction of the housing. The plurality of tabs is arranged next to each other in a sequence having a row distance that corresponds to a first grid distance of the connector holders of the switching device. At least one end, relative to the lengthwise extending, of the cross connection link has incoming contact openings leading to the conductor rail.
