The PZ type distribution box consists of a cabinet, molded-case circuit breakers, miniature circuit breakers, residual current circuit breakers, electricity meters, PVC insulated wires, copper busbars, neutral busbars, protective earth busbars, insulators, and electricity meter connectors. The cabinet is constructed from cold-rolled steel sheet, bent and partially welded.
Distribution boxes are widely used devices in low-voltage power systems, designed for power distribution and control. Suitable for various building, industrial, and commercial environments, they enhance the reliability and safety of power systems. The product features a compact design for easy installation, a well-organized internal structure for convenient maintenance, and meets the electrical needs of diverse users.Both inlet and outlet units are equipped with operating panel covers. These covers shield live parts, providing IP20C protection, while the enclosure protection rating is IP30. The cabinet is coated with epoxy powder electrostatic spraying.
