MB4000-TA welding switchgear is suitable for AC 50HZ, rated voltage 480V, rated working current to 4000A power distribution system, as power and other equipment. This switchgear meets the GB/T7251.12-2013 "low voltage switchgear and control equipment" and other standards.
After the main features:
1. The switch cabinet is mainly composed of a cabinet body, a cabinet door, electrical components, bus, bus bars, insulation support, accessories and other components.
2. The frame of the switch cabinet adopts a welded structure, which has high strength and strong structure. The front door, side plate and top cover of the cabinet are all coated with surface electrostatic powder, and the coating is uniform and beautiful and corrosion resistant.
3. The auxiliary circuit uses line grooves, spiral winding tubes, buckle end belt and so on to fix the wire harness. The wiring harness is evenly arranged and the structure is beautiful and reasonable.
4. The size of the cabinet and the way of import and export can be selected according to the actual needs of the field, and the installation of all kinds of fittings is convenient. The metal parts in the cabinet are connected reliably, and the main grounding points and the grounding signs are protected. The whole cabinet forms a complete grounding protection system, so as to ensure the safety of operation and operation.
