410 / 412 MV Junction Box



FPS Swivels

The Model 410 medium voltage (MV) junction box is designed to join two three phase circuits, up to 15 kV / 650 A, using single or multicore MV power cables. The Model 412 is a larger junction box, rated up to 36 kV / 400 A. There is sufficient space inside the enclosure to allow for MV cable termination and routing of cables. There are facilities for connection of cable ground conductors and ground straps from the stress control sleeves.

The junction box is certified as a flameproof (Ex d) enclosure. Ingress protection is IP66 / IP68-20 m. For power cables that include optical fibers, a fiber breakout facility is available.
