Boxes junction KVMK [ХХХХХХ] 1ExeIIBT5Gb are intended for making connections (branches) of electrical circuits of general and special purpose (power circuits, control circuits, signaling, etc.) in hazardous areas. & Nbsp; Boxes are designed to enter armored, non-armored electrical cables of circular cross-section and cables in metal hose.
The boxes are supplied with screw (up to 25 mm2) or spring (up to 16 mm2) terminal clamps, which are mounted on a DIN rail. Boxes can contain a different number, type and location of terminal clamps, which are specified when ordering. Inside the enclosure, additional earth or shielding busbars can be installed.
The boxes are supplied with explosion-proof cable entries of the KV series TU 3449-138-81888935-2016 produced by OOO & la company SMD. The type, number and location of the cable glands is specified when ordering. Each cable entry is supplied with rubber seals for the cable.
