A medium voltage switchgear or control gear includes at least one first compartment; a cable compartment; a plurality of main components; and a plurality of auxiliary components. The plurality of main components is housed in at least one part of the at least one first compartment. The plurality of auxiliary components is housed in the cable compartment. The second connector is configured to connect to the first connector to connect a cable in the cable compartment to a component of the plurality of main components. The cable compartment is configured to be disconnected from the at least one first compartment and wherein the cable compartment is configured to be spatially separated from the at least one first compartment.

A motor control center (MCC) for an industrial automation system, includes an enclosure housing comprising a plurality of sections, including a first section having one or more buckets, including a first bucket, a first bus bar, a second bus bar, and a third bus bar extending horizontally across the first section along a back plane of the enclosure housing, and a first electrical component, configured to perform one or more functions of the MCC, disposed within the first bucket of the first section. The first electrical component is directly electrically coupled to the first set of bus bars such that the first electrical component draws a first phase of power from the first bus bar, a second phase of power from the second bus bar, and a third phase of power from the third bus bar.

A busbar board (1) for connection of devices (11) to a power busbar system, wherein the busbar board (1) comprises a front side touch protection cover plate (2) having feedthrough openings (7) for electrical connection contacts (13) of devices (11) to be connected to the busbar board (1), wherein the touch protection cover plate (2) is adapted to cover power busbars (6) having contact openings (5) lying directly beneath the feed-through openings (7) of the touch protection cover plate (2) and comprising a touch protection base plate (3) connected to said touch protection cover plate (2), wherein the touch protection base plate (3) covers the power busbars (6) enclosed by the busbar board (1) from behind, wherein a power feed-in of electrical power into the power busbars (6) enclosed by the busbar board (1) is provided by power feed-in plugs (10) being pluggable into socket (26) of the touch protection base plate (3) of the busbar board (1).

A passive arc control system for a motor control center 60 includes an arc attenuating box having sides separating adjacent vertical bus bar phases 54, providing a physical barrier to arc flash energy. The box is open at its top and bottom forming a chimney 55. A shutter assembly for each box includes an insulator cap 62 on a free end of the bus bar and an independently moveable, box-shaped shutter 64 that slides along the bus bar away from the insulator cap, when a device is connected to the bus bar. The shutter has an opening 65 through which the bus bar passes when the device is connected to the bus bar and an opening 55′ aligned with the box's chimney. The arc control system provides a high degree of arc protection for personnel working around open motor control centers and is highly modular and easy to construct.
