PXT distribution box and PZ box

PXT distribution boxes are versatile power distribution units for industrial and commercial use, while PZ boxes, such as the PZ30, are compact lighting and power distribution boxes for residential and commercial circuits.

PXT Distribution Box

Function and Applications: The PXT distribution box is used in power plants, substations, factories, mines, and high-rise buildings for distributing electricity safely and efficiently. It supports AC systems of 400V and below and provides overload, short-circuit, undervoltage, and leakage protection for frequent conversion and low-power lines. It is suitable for lighting, power feed, and other electrical purposes.

Design and Components: PXT boxes include a face cover, box body, transparent cover door, installation rail, conductive bar, incoming line shield, and bus baffle. They also provide neutral line and grounding terminal blocks. The shell can be all-plastic, plastic-faced iron bottom, all-steel, or stainless steel, depending on user requirements.

Various circuit solutions can be combined, and the boxes can be surface-mounted or concealed. Specifications: Rated current and short-time withstand current can be customized (e.g., 250A/10kA). Inlet style options include single-phase, three-phase, or mixed input.

Outlet circuits can be single-phase or three-phase. Main switch type and protection level are configurable (e.g., IP30),.

P

Z Box (PZ30)Function and Applications: The PZ30 lighting distribution box is designed for single-phase and three-phase circuits with a frequency of 50Hz, rated voltage up to 500V, and load current not exceeding 100A. It is used for power and lighting distribution, motor control, and provides overload, leakage, and short-circuit protection. It is widely applied in factories, buildings, residential areas, and shopping malls.

Design and Components: PZ30 boxes are constructed with 1. 0mm thick high-quality steel plates and feature high-voltage electrostatic spray coating. They have a transparent plastic cover, pre-punched knockouts for cable entry/exit, and flame-retardant materials.

The design allows heat dissipation, structural strength, and easy modification, making it suitable for future expansion. Standards Compliance: PZ30 boxes comply with GB7251. 3 and IEC 60439-3, ensuring safety and reliability for ordinary users.
