Product Features

1. Aluminum alloy shell is formed by die-casting or steel plate welding, with high-voltage electrostatic spraying on the surface for a beautiful appearance;

2. There are multiple specifications of sockets for easy maintenance. When ordering a power supply, users must indicate the number of circuits in the distribution box, the circuit current, and the number of poles of the circuit breaker. If there is a main switch, it is necessary to indicate the total switch current and number of poles, as well as the direction, quantity, and size of the inlet and outlet. If lighting, power, and leakage are mixed, a schematic diagram must be provided.

6、 Due to the variety of product changes, the external installation dimensions and assembly forms need to be disclosed to the customer and provided separately.

3. Modular structure, various circuits can be freely assembled according to needs;

4. Steel pipe or cable wiring.

5. It can be equipped with a main switch, overload and short circuit protection functions, and can be equipped with leakage protection function according to user requirements.
