The PZ30 Low Voltage Distribution Box is designed for power distribution, lighting systems, and motor control applications. It provides reliable protection against overload, short circuit, leakage current, and overvoltage, ensuring safe and stable operation of electrical equipment.
It is widely used in industrial and civil buildings, manufacturing facilities, mining enterprises, commercial complexes, railway stations, hospitals, schools, and residential buildings, as a terminal power distribution solution.
The product is suitable for AC 50Hz systems, with rated voltages of 220V (or 380V) and a total load current not exceeding 100A. It is designed for single-phase three-wire or three-phase five-wire terminal circuits, providing control and protection for end-use electrical equipment.
The PZ30 distribution box adopts a modular design based on 9mm standardized electrical modules, allowing flexible configuration according to different application requirements. Components can be easily assembled and disassembled, ensuring fast installation and maintenance. The operating handles of circuit breakers are externally accessible for convenient operation.
The enclosure is designed with knock-out cable entry points on five sides (excluding the cover), facilitating flexible wiring and installation.
