A support box (60) for supporting functional elements within the frame (28) of an electrical connection enclosure comprises at least one pair (70) of rails (72) for guiding a monitoring/control plug-in unit forming a functional element in translation, a parallelepipedal framework (62) and members for fastening the framework to the frame. The framework comprises two horizontal plates, a vertical back that is perpendicular to the horizontal plates, and two vertical walls, each supporting a rail of each pair of rails. The members for fastening the framework to the frame comprise fastening lugs that are elastically deformable and integral with the horizontal plates and elastically deformable load absorbing lugs that are integral with the vertical walls. The support box comprises at least one centring pin, vertically centring the box with respect to a post (32) of the frame, each centring pin being arranged in a positioning hole of a fastening lug.

WELDED BOARD AND ELECTRICAL CABINET STRUCTURE presents a cabinet built with welded frames that use vertical and horizontal profiles, having an internal fastening wall with holes and cutouts to the fitting of a cage nut and an internal fastening tab, a side sealing surface, a front sealing surface and the isolation barrier, the structure being assembled with at least two welded frames, which are assembled in parallel and joined through four depth profiles, said depth profiles being joined directly to the welded frames vertices.

A cooling system for an air insulated switchgear compartment includes: a housing; a fan; and a flap. The fan is mounted to the housing. The flap is mounted to the housing. The flap is positioned adjacent to the fan such that a rotational axis of the fan does not extend through the flap.

The invention relates to a switch cabinet with at least one brush strip for the conductor feed-through, the switch cabinet having a switch cabinet frame with a horizontal or vertical profile frame from which a profile web extends, wherein the brush strip is placed on a free end of the profile web with bristles extending from the profile web over the inner circumference of the profile frame.

Systems and methods for mounting a panel to a wiring cabinet are provided. The wiring cabinet can include a frame profile with a frame profile opening and the panel can have a panel opening. A fastening element used to mount the panel to the wiring cabinet can include an expanding rivet with an opening and at least two rivet legs. The expanding rivet can be received through the panel opening and the frame profile opening when aligned. The fastener can also include an expanding body that can be inserted into the opening of the expanding rivet so that the rivet legs are forced apart to cause the rivet legs to engage the frame profile.

An electrical cabinet includes a cabinet frame, two or more hoist brackets, a hoist bar, and a hoist mechanism. The cabinet frame has a top section and a bottom section. The bottom section rests on an underlying supporting surface, and the top section is positioned at an opposing side of the cabinet frame from the bottom section. The hoist brackets are coupled to the top section of the cabinet frame. Each of the hoist brackets has a respective indentation. The hoist bar rests in the indentations of the two or more hoist brackets, and includes a first groove. The hoist mechanism rests in the first groove of the hoist bar. The hoist mechanism is configured to facilitate lifting and positioning of an electrical component of a power distribution system within the electrical cabinet. The electrical component can be a bus assembly for a switchboard.

The invention relates to a switch cabinet having a frame and a sidewall element mounted thereon, wherein the sidewall element is mounted on the frame via at least one latch lock, the latch lock having a latch and a latch receptacle one of which is fixed to the frame and the other of which is fixed to the sidewall element and which are accommodated in a volume which is open towards an outer side of the frame and which is delimited on the one hand by a folded profile edge of the frame and on the other hand, adjoining the folded profile edge on the outer side, by the sidewall element.

A multipolar electrical protection system including a plurality of devices for switching an electric current. Each switching device has a plurality of compartments each comprising an extinguishing chamber and a pair of separable electrical contacts that are connected to upstream and downstream connection terminals, the separable electrical contacts being movable between open and closed positions under the action of a tripping device. The switching devices are separate from one another, while the upstream terminals of each device are connected by a first connector in order to keep them at one and the same electrical potential and the downstream terminals of each device are connected by a second connector in order to keep them at one and the same electrical potential. The switching devices are controlled by one and the same common tripping device.

A center post assembly for eliminating sagging of a roof panel in a cabinet, where doors of the cabinet latch to the post assembly. The post assembly includes a base portion and a post portion, where one of the base portion or the post portion includes a plurality of slots and the other one of the base portion or the slot portion includes a plurality of threaded studs. The base portion further includes a first bracket and a jackscrew threaded into a threaded opening in the first bracket and the post portion further includes a second bracket, where the jackscrew engages the second bracket so that rotation of the jackscrew causes the second bracket to move relative to the first bracket so that the studs slide in the slots and increase the length of the post assembly to remove the sag.

A fastening device for fastening a DIN rail to a wall includes: at least one fastening element having a wall fastening portion for fastening the fastening element to the wall, and a DIN rail fastening portion for fastening the fastening element to the DIN rail. When in a fastened state, the DIN rail fastening portion is guided at least in some regions through an opening formed in the DIN rail. The DIN rail fastening portion includes a tongue and groove system into which a portion of the DIN rail is inserted in the fastened state.
