Indoor Closed Power Distribution Cabinet XL-21

Timetric Electric Indoor closed power distribution cabinet XL-21 (21 cabinet for short), the "XL" series also includes XL-20 (20 cabinet), XL-28 (28 cabinet), etc. The difference between them is the different voltages in the cabinets. Taking the 21 cabinet as an example, the voltage is often not more than 500V.

The "XL" series is called a power cabinet（Indoor closed power distribution cabinet XL-21）, which can actually be regarded as a large distribution box, often used in terminal circuits.

The difference between it and other cabinet types is that it is a large distribution box because of the following reasons:

1. The main busbar is not fixed;

2. The isolating knife switch is opened forward;

3. It is only responsible for the lower end load and only loads the maintenance load.

It is suitable for power plants and industrial and mining enterprises, three-phase three-wire, three-phase four-wire, and three-phase five-wire systems with AC voltage of 500V and below, for power lighting and power distribution. It is also suitable for making various motor starters, including full-voltage direct starter, full-digital control soft starter, auto-coupling step-down starter, star-delta starter, multi-speed motor starter, etc.

Working Environment：

The use environment requirements ofTimetric ElectricIndoor closed power distribution cabinet XL-21, humidity, altitude, air quality and other aspects.‌

1. Ambient temperature: -50°C~+40°C, the average temperature within 24h shall not exceed +36°C;

2. Altitude: not more than 2000m;

3. Relative humidity: not more than 50% when the ambient air humidity is +40°C; at lower humidity, there may be higher relative humidity (e.g. 90% at +20°C), and moderate condensation is allowed considering the temperature change.

The inclination between the vertical plane and the equipment should not exceed 5°. The equipment should be installed in a place without severe vibration, impact or corrosion.

Advantages and features of switchgear

The main features and advantages ofTimetric ElectricIndoor closed power distribution cabinet XL-21 include the following aspects:
