Basic introduction of outdoor rainfall power distribution cabinet
Rain -proof power distribution cabinets are widely used in building lighting and small power control circuits of hotels, apartments, high -rise buildings, ports, stations, airports, warehouses, hospitals, and factory and mines. In the indoor lighting and power distribution lines with a current of 450V and below, the current is 250A and below, it is used as a line overload protection, short -circuit protection, and line switching. This type of equipment is suitable for the venue that civilian use or non -professional personnel can enter. The product complies with the standards of the “Low -voltage complete set switching equipment”.
The box design will be closed safely with the power site, the switching handle is exposed to the box cover, which can be operated outside the box. Open the lid can be maintained.
The power distribution box is equipped with a neutral line terminal (or copper volley) corresponding to the output circuit and the ground protection line terminal (or copper volume);
