A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

An interlock system for a low, medium or high voltage switchgear includes: a compartment; a door; a door handle; and a circuit breaker. The door permits access to an inside of the compartment. The door handle opens and closes the door. The circuit breaker is located in the compartment. The door handle is movable from a closed position to an open position. When the door handle is in the closed position, the door does not to open, and when the door handle is in the open position, the door opens. A movement of the door handle from the closed position to the open position places the circuit breaker in a locked configuration. In the

A panelboard assembly having common components is disclosed. The panelboard assembly includes base rails, a first bus support extending between the base rails, the first bus support accommodating different thickness buses, buses coupled to the first bus support, and one or more breaker mounting barriers received over top of the buses. In some embodiments, the one or more breaker mounting barriers accommodating different width buses. Methods of assembling the panelboard assembly are disclosed, as are other aspects.

A carrier rail housing (1) is described comprising a snap-in base (2) for setting on a carrier rail (3). The snap-in base (2) comprises a carrier rail receiving opening (5) for receiving a carrier rail (3), two snap-in latches (4, 12) movable relative to each other comprising respectively at least one snap-in lug (6, 13), which protrude in a snap-in position into the carrier rail receiving opening (5) for locking with a carrier rail (3) receivable in the carrier rail receiving opening (5), and a coupling element (10) which is in operative connection with the two snap-in latches (4, 12) and transfers a movement of one snap-in latch (4) into a movement of the other snap-in latch (12). The snap-in base (2) further comprises a locking arm (15) with a stop (18) protruding into the carrier rail receiving opening (5) in an open position, in which the snap-in lugs (6, 13) are unlocked from the carrier rail (3), for applying at a side edge of the carrier rail (3) receivable in the carrier rail receiving opening (5). The locking arm (15) is in an operative connection with the snap-in latches (4, 12) in such a way that the snap-in latches (4, 12) are held in the open position by the application of the stop (18).

A rail fixing system comprises a rail fixing arrangement adapted to fix the rail fixing system to a profile rail, a system coupling arrangement adapted to fix the rail fixing system to another rail fixing system disposed adjacent to the rail fixing system on the profile rail, and an actuation device common to the rail fixing arrangement and the system coupling arrangement. The actuation device is connected to a first positive-locking connection element of the rail fixing arrangement and a second positive-locking connection element of the system coupling arrangement. The actuation device is supported on a resilient element and the first positive-locking connection element, the second positive-locking connection element, and the resilient element are arranged along a straight line that extends in an effective direction of the resilient element.

The present disclosure provides a coupling system for coupling a medical accessory to an accessory support is provided. The present disclosure also provides a system for powering a medical accessory with an accessory support.

There is provided a rail attachment apparatus for an electrical device in which a biasing elastic function is imparted to a slider itself, whereby the slider can be adjusted to be thin and the number of components can be decreased. The rail attachment apparatus includes a nipping portion that nips one side edge of an attaching rail fixed to an attaching surface of the electrical device, and a slider that is opposed to the nipping portion and slidably held at the other side edge of the attaching rail in a direction intersecting with this attaching rail. The slider is provided with integrally formed bending elastic portions which bias the slider in a direction to enable nipping the attaching rail.
