design
The box body is made of corrosion-resistant sheet steel. The box consists of a body and a cover connected by bolts. The housing can be of two types - with a removable lid and with a hinged lid. A mounting panel is installed inside the case, on which DIN rails with terminal clights, grounding bars and other electrical equipment can be installed. Explosion-proof cable entries, couplings, plugs, valves, etc. can be installed on the sides of the box. Also, removable panels can be installed on the sides of the box. All fastening and mounting elements are made of corrosion-resistant steel.
