China PZ30 Lighting Distribution Box - Reliable Electrical Solutions from Leading Suppliers and Factory

PZ30 series lighting distribution boxes are widely used in high-rise buildings, hotels, hospitals, restaurants, stations, ports, airports, computer rooms, laboratories, schools, industrial and mining enterprises and civil buildings. They are used for overload, short circuit and leakage protection energy metering in lighting and small-capacity power lines with AC 50~60Hz, rated voltage up to 400V in three-phase systems and voltage at 230V in single-phase systems, with a total current of 100A and below. They can also be used for infrequent on-off lighting lines, daily electrical appliances and small-capacity motors under normal conditions.

The product complies with the standard: GB7251.3 "Low-voltage complete switchgear and control equipment, Part 3: Special requirements for low-voltage complete switchgear and control equipment for sites accessible to non-professionals - distribution boards".

• Altitude not exceeding 2000m;
• Ambient temperature: -5℃~+40℃, the average value within 24 hours shall not exceed +35℃;
• The monthly average relative air temperature at +20℃ shall not exceed 90%;
• Atmospheric conditions: The relative humidity of the air at the installation site shall not exceed 50% when the ambient maximum temperature is +40°C, and the maximum relative humidity of the month shall be 90% when the average minimum temperature in the wet month is +25°C.
• A place without severe vibration and impact;
• There is no explosion hazard, and the medium does not contain gases and conductive dust that are sufficient to corrode metals and damage insulation.

The design of this distribution box meets the strict requirements of GB7251.3 standard (which applies to low-voltage complete switchgear and control equipment). PZ30 is particularly suitable for environments that are easily accessible to non-professionals, ensuring safe and reliable daily use. Its design allows infrequent switching operations on lighting circuits, daily electrical appliances and small-capacity motors under normal circumstances, making it a practical solution for residential and commercial installations.

The operating parameters of the PZ30 lighting distribution box have been carefully designed to ensure optimal performance. It is designed to operate effectively in environments with an altitude of no more than 2000 meters and a temperature range of -5℃ to +40℃. The 24-hour average temperature must not exceed +35℃, and the monthly average relative humidity at +20℃ should be kept below 90%. These specifications ensure that the distribution box operates reliably in a variety of environmental conditions and is suitable for a variety of applications.

Installation conditions are critical to the performance of the PZ30 lighting distribution box. It is important to install the distribution box in a location free from severe vibration and shock, as these factors may affect its integrity and functionality. The installation location must be free from explosion hazards and should not contain gases or conductive dusts that could corrode metal parts or damage insulation. Following these guidelines will help maintain the life and reliability of the distribution box.

The PZ30 lighting distribution box is a rugged and reliable solution for power distribution management in a variety of environments. It complies with industry standards and is able to operate under specific environmental conditions, making it an ideal choice for high-rise buildings, hotels, hospitals and other places. By understanding the functions and requirements of the PZ30, users can ensure safe and efficient power distribution, ultimately improving the performance of their electrical systems.
