An apparatus for securing an electronic component to a DIN rail including an electronic component, a latching system positioned on an end of the electronic component adapted for attachment to the DIN rail, wherein the latching system is made of a plastic material, wherein the DIN rail has a flat upper surface with two legs extending downwardly from, and perpendicular to, the flat upper surface, and a flange extends outwardly from each leg, wherein the latching system includes a recess, an upper surface above the recess having an angled slot positioned in the upper surface adapted to receive an upper flange of the DIN rail, and a lower surface below the recess adapted to have an end of a lower flange of the DIN rail positioned thereover.

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 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).

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.

A retention mechanism for attaching equipment to a mounting rail comprises a slider including a first retention section and a pivoting lever mechanical coupled to the slider. The slider is movable in a translational manner along a sliding direction with respect to a remaining portion of the retention mechanism. The lever includes a second retention section aligned with the first retention section in the sliding direction. A reception area for receiving the mounting rail is defined between the first retention section and the second retention section.

An ejector can be provided for a surge protection module that is configured to be engaged with a base for operation. The ejector can include a lever that is configured to pivot relative to the base to eject the surge protection module from engagement with the base.

An electronics module includes a housing having a mounting foot or component suitable for mounting on a support rail and for fastening the electronics module to the support rail which is mounted on a mounting base. At least one spring element is provided in the lower region of the housing facing the mounting base when mounted. The at least one spring element is configured to provide a damping effect when the housing vibrates relative to the mounting base.

A switching device having a housing, with a cover that can pivot about a rotational axis, and a securing device for carrier rail mounting. The cover has at least one coupling contact for an electrical and/or signal-type contact connection with at least one engageable switching device. A closing or releasing of the contact connection occurs with a pivoting of the cover. A locking or unlocking of the securing device occurs with a pivoting of the cover. The securing device has a spring-elastic clipping element shaped on the housing, for force-locking securing to a carrier rail end face, and has a sliding element, which is mounted such that it can slide in a linear manner within the housing and is coupled to the cover, for interlocking securing to the carrier rail end face opposite the clipping element.

A fixation bracket has: a housing; an elastic rail receiving structure disposed along a bottom of the housing; and a connection arm connected to the elastic rail receiving structure and having one end extending above the housing.
