PZ40 Electricity Meter Box (Meter Box) Series
Usage Features
PZ40 modular terminal combination electrical appliance (PZ40 distribution box is suitable for single-phase three-wire or three-phase five-wire terminal circuits with AC frequency of 50Hz, rated working voltage of 220V or 380V, and rated current not exceeding 100A. It controls and distributes power to electrical equipment and protects against overload, short circuit, leakage and undervoltage of the line. It can be widely used in modern hotels, commercial buildings, industrial and mining enterprises, residential buildings and other buildings.

Product Features
The main structural components of the terminal combination electrical appliance include transparent cover, upper cover, box, mounting rail, conductive bar, wiring, double-wire cover and electrical switch components. The internal electrical switch components are all electrical components with a width of 9mm, installed on the top hat track, and can be combined arbitrarily according to needs. The disassembly and assembly are quick and convenient. The switch component handle is exposed, and the live and other parts are covered inside the upper cover. It can be easily operated by opening the door, and it is safe and reliable to use. There are inlet and outlet holes on the top, bottom, left, right and back of the box for easy wiring.
Product Introduction
A key feature of the PZ40 meter box is its operational reliability in specific environmental conditions. The device is designed to operate optimally in an ambient temperature range of -5°C to +40°C. This high temperature resistance ensures that the meter box can be installed in a variety of climate conditions without any loss of performance. Its humidity level is carefully designed to achieve a maximum relative humidity of 50% at +40°C and can be flexibly adjusted to 90% at lower temperatures (such as +20°C). This adaptability makes the PZ40 suitable for a variety of installation environments.
The PZ40 meter box installation requirements are also worth noting. It is classified as a Class II installation, which means it is suitable for environments where transient overvoltages are expected. The pollution degree is 3, which means the device can operate effectively in areas with moderate pollution levels. The installation altitude must not exceed 2000 meters to ensure that the meter box can maintain its integrity and functionality in different geographical locations.
The structural design of the PZ40 meter box is another highlight of its ease of use. The main components include transparent cover, upper cover, box body, mounting rail, conductive strip, line, double-line cover and electrical switch elements. The transparent cover allows easy observation of internal components for maintenance and monitoring. The built-in electrical switch elements adopt a 9mm modular width, can be installed on the top hat rail, and can be flexibly configured according to user needs. This modular design ensures that the meter box can be customized according to specific power needs.
The PZ40 meter box is designed with safety and convenience in mind. The switch element handles are exposed for easy operation, while live parts are securely covered in the upper cover. This thoughtful design minimizes the risk of accidental contact with live parts, thereby improving user safety. Multiple access holes are provided on the top, left, right and back of the meter box for easy wiring and installation. The PZ40 series meter box is a reliable and efficient power distribution solution that combines safety, flexibility and ease of use.
