Basic Information
Enclosure:
Cabinet enclosures are made from hot-dip galvanized profiles and DX51D+Z275 sheet steel, with a thickness of 1–2 mm. They are painted with standard RAL7032 color (other colors can be applied according to the project). Cabinets are connected to each other using joining bolts. The cabinet enclosures are assembled structures with surfaces coated in durable powder coating. Doors are fitted with hinges, and locks are made of stainless steel. The cabinets are prepared for interconnection and feature lifting lugs. Current and voltage measuring instruments and control buttons can be mounted on the doors. Automatic circuit breakers and fuse-switch blocks can be installed inside the cabinet or positioned so that their front panels and control handles are on the outer side of the cabinet doors.
