Wall-Mounted Industrial XL-21 Steel Enclosed Electrical Control Panel
The XL-21 type power cabinet is suitable for power plants and industrial enterprises, used in three-phase four-wire or three-phase five-wire systems with an AC voltage of 500V or less for power distribution. The XL-21 type low-voltage power cabinet is an indoor device installed against the wall, with maintenance performed in front of the screen. The enclosure is made by bending steel plates, and the switch operating handle is located on the upper right column of the box, which can be used to switch the power supply. Depending on user needs, different types and current ratings of circuit breakers can be selected to meet the requirements of different users.
