The XM type distribution box is suitable for single-phase, three-wire or three-phase five-wire terminal circuits with a rated voltage of 220 or 380V and a single-row load total current not greater than 80A. The overload, short circuit, leakage, and over-voltage protection of the device are used by non-professionals and do not require maintenance. The bottom box of the distribution box is made of high-quality cold-rolled steel plate, and the surface is sprayed with plastic, which has the characteristics of non-deformation, non-oxidation, and corrosion resistance.
