Product Overview
The PZ Series distribution box is a basic terminal distribution device for residential and industrial low-voltage power distribution systems. It is mainly used in AC 50Hz, rated voltage 220/380V distribution circuits to achieve circuit distribution, overload protection, short-circuit protection, and power control. The product features a standardized structure and neat wiring, which can reasonably distribute electrical loads, effectively prevent the spread of low-voltage circuit faults, and ensure the safe and stable operation of end-user electrical equipment. It is an essential terminal distribution device for residential construction, industrial and mining facilities, municipal engineering, commercial complexes, and residential buildings.
The product adopts a high-quality cold-rolled steel sheet enclosure with electrostatic spray coating for anti-corrosion treatment. It strictly follows national electrical industry standards, offering advantages such as good protection, convenient installation, safety, reliability, and high cost-effectiveness. With a compact structure and neat appearance, it is suitable for indoor conventional distribution scenarios and is widely used in various residential buildings and industrial low-voltage distribution systems.
Operating Environment
1. Ambient Temperature: -20℃ to +45℃, suitable for conventional indoor ambient temperatures, resistant to daily temperature variations.
2. Altitude: ≤1000m; installation conditions can be adjusted for higher altitude areas to meet insulation requirements.
3. Relative Humidity: ≤95% (at 25℃); the enclosure is sealed and moisture-proof, preventing internal components from moisture aging and short-circuit faults.
4. Installation Location: Indoor walls, electrical rooms, hallways, equipment rooms, etc.; free from corrosive gases and explosive dust; well-ventilated and dry.
5. Protection Level: IP30, effectively preventing dust and foreign object intrusion, protecting the safe operation of internal switching components.
6. Installation Requirements: Wall-mounted flush or surface fixed installation; reliable and firm grounding; reserve space for heat dissipation; avoid installation in humid, enclosed environments.
