A method for installing a heavy and bulky switching module, in particular a static transfer switch, in an electrical cabinet, by way of an installation kit to make the switching module easily removable and interchangeable, regardless of its size and weight. The electrical cabinet is equipped with the installation kit including at least two support rails, extendable between an extended position outside, and a retracted position inside, the electrical cabinet, and forming two parallel rolling paths. The switching module is equipped with rollers in two parallel rows, arranged to circulate on the rolling paths to enable movement of the switching module relative to the electrical cabinet by pushing and pulling with minimal effort. A raised transport pallet is also used to facilitate handling of the switching module outside of the electrical cabinet by a simple industrial truck, without resorting to a lifting device.

A support rail on which a plurality of housings, which can be strung together and which are equipped with electrical contact elements and/or functional elements, can be arranged is mounted onto a mounting base in a mounting position, even in a state in which the housings have already been strung onto the support rail prior to the support rail being mounted. The support rail is retained by two or more latching devices which are placed in position on the mounting base prior to the support rail being mounted. The latching devices and the support rail are configured such that the support rail can be placed onto the latching device and locked onto it without using any tools. The latching device has a base section has a cross-section relative to the mounting position on the mounting base which corresponds to a U rotated by 180°, The base section is divided into a horizontal base bar and two side bars perpendicular thereto and the latching element is supported on the mounting base as a thrust bearing via the two side bars.

An electrical/electronics power distribution cabinet is disclosed which includes internal components enabling the cabinet to be quickly and easily reconfigured for allowing all cabling to exit an upper end of the cabinet or a lower end of the cabinet. The cabinet includes fully isolated top and bottom panelboard circuit breaker areas and a movable internal wall portion that helps to form an isolated compartment to route electrical cabling within the interior area of the cabinet, while keeping the cabling associated with the two panelboard circuit breaker areas fully separate from one another. This enables access to one of the top or bottom panelboard circuit breaker areas for service or reconfiguration without the need to access the other.

A three phase switchgear or control gear includes: at least one compartment; a plurality of components for a first phase; a plurality of components for a second phase; and a plurality of components for a third phase. The plurality of components for the first phase, the plurality of components for the second phase, and the plurality of components for the third phase each include a main busbar, a three position linear or rotational movement disconnector switch, a single phase circuit breaker pole, and a cable connection. The plurality of components for the first phase, the plurality of components for the second phase, and the plurality of components for the third phase are housed in the at least one compartment.

In a power conversion device, cable connection positions of connections in which a plurality of bus bars is respectively connected to external line cables are non-overlapping with each other as viewed from a side on which the external line cables are pulled out.

The present disclosure envisages a housing (1000). The housing (1000) has an operative upper compartment (200) and an operative lower compartment (100). A first lid (110) and a second lid (210) cover the lower and the upper compartments (100, 200) respectively. The lid (210) is openable. A panel (400) is configured to be inserted between the lower compartment (100) and the upper compartment (200) thus forming a partition between the compartments. The housing (1000) of the present disclosure, when utilized for housing data distribution elements and electrical power distribution elements separately in its compartments, provides safe access to the data distribution elements and prevents risk of touching live electrical components.
