XL-21 low voltage power distribution cabinet
Product Details
Product overview
XL-21 type power distribution cabinet is used in industrial and mining enterprises, civil buildings, schools and government places, with an AC frequency of 50Hz, and is used for power or lighting distribution in power distribution systems such as three-phase three-wire, three-phase four-wire, and three-phase five-wire AC voltage below 500V. The shell is bent from steel plate and has the characteristics of compact structure, convenient maintenance and flexible combination of circuit schemes. In addition to air circuit breakers and fuses as circuit breaker protection, the power distribution cabinet can also be equipped with contactors and thermal relays. The front door of the box can be equipped with operation buttons and indicator lights. When a knife switch is required, the knife switch operation handle is installed on the upper part of the right column in front of the box, which can be used for switching power supply, after the door is opened, all equipment in the distribution box is exposed for maintenance. The distribution box adopts the new components designed by ourselves in China, and has the characteristics of compact structure, convenient maintenance and flexible combination of circuit schemes.
