Explosion protection is ensured by a protection class "d" - explosion-proof casing.
RIZUR-KC-DB have a housing made of aluminium alloy using pressure-die casting. The box consists of a housing and a lid with an explosion-proof flange connection, tightened with captive screws. The lid is attached to the housing with hinges.
Inside the housing there’s a mounting panel, DIN-rails with terminals, and grounding buses. Side walls can have explosion-proof cable glands installed for different types of cables. The bottom part of the box has assembling channels with openings for the assembly bolts. All the fastenings are made of corrosion-resisting steel.
