High current enclosure for up to 3kA

This high-current enclosure offers enhanced flexibility using a range of tinned copper busbars mounted in a tiered arrangement. The SX busbar provides termination for cables carrying up to 3000 Amps.

The arrangement of busbars in this enclosure can be tailored, allowing a variety of configurations suitable for inflexible, higher-current carrying cables. These are housed within a 316L (1.404) stainless steel enclosure that is both IP66 and Type 4X rated and DTS-01 deluge tested.

Suitable for high current, medium voltage installations. The SX Busbar can accommodate up to five conductors per phase, plus neutral with an optional earth bar facility. All in a bottom or top entry-only configuration. The full load current is determined per connector and is size-dependent.

This enclosure is ATEX and IECEx approved for use in areas where potentially explosive gas and dust may be present.
