ProductDescription：
The XL-21 power cabinet is suitable for power distribution in three-phase four wire or three-phase five wire systems with AC voltage of 500V or below in power plants and industrial and mining enterprises. The XL-21 low-voltage power cabinet is an indoor device installed against the wall, with maintenance in front of the screen. The outer shell is made of bent steel plate, and the switch operating handle is located on the upper right column in front of the box. It can be used to switch power supply. Different models and current levels of circuit breakers can be selected according to user needs to meet the needs of different users.
Applicationfield：
The XL-21 power cabinet is suitable for factories and mining enterprises such as light textile, metallurgy, chemical, mining, and machinery. It is used as a low voltage distribution system with AC 50Hz, rated voltage of 380V or 660V, and rated current up to 630A for three-phase three wire, four wire, or five wire power distribution. It is used for power and lighting distribution. At the same time, it can also be used for partial control in low-voltage control systems.
