XL-21 low voltage power distribution cabinet

XL-21 low voltage power distribution cabinet

Product Description

XL-21 low-voltage power distribution cabinet is a new type of domestically designed components for BOKR Electric.

The shell is made of steel plate, with compact structure, convenient maintenance, and flexible circuit scheme Combination and other characteristics; in addition to the installation of air circuit breakers and fuses as circuit breaker protection.Equipped with contactors and thermal relays, the front door of the box can be equipped with operation buttons and indicators, and a knife switch is required.

At the time, the knife switch operating handle is installed on the upper right column of the front of the box, which can be used to switch the power supply and power distribution.

There is a door in the front of the box. After the door is opened, all the equipment in the distribution box is exposed for easy maintenance.

XL type Power distribution cabinets are used in industrial and mining enterprises, civil buildings, schools and institutions, and exchange frequency. Single-phase and three-phase, 50Hz ^ 60Hz, load current below 630A, IT system below 500V, TN-C system, TT system (formerly known as three-phase three-wire, three-phase four-wire power system) for power and lighting For power distribution.

Low Voltage Switchgear Working environment:
1.Ambient temperature: -5 ℃ ~ + 40 ℃, and the average temperature within 24h not exceed + 35 ℃.
2.Altitude: not exceed 2000m.
3.The ambient air temperature of + 40 ℃ not more than 50%; at lower temperatures can have a higher relative humidity on (eg: + 20 ℃
at 90%), taking into account the change in temperature allows the generation of a moderate condensation.
4.Equipment installation and the vertical gradient should not exceed 5 °
5.Equipment should be installed in the absence of severe vibration, shock-free and corrosion-free place
