The XL-21 low voltage enclosed power cabinet is suitable for three-phase three-wire, three-phase four-wire, and three-phase five-wire systems with an AC voltage of 500V and below in power generation and industrial and mining enterprises. For power lighting and power distribution. The XL-21 low-voltage power cabinet has the characteristics of flexible power distribution scheme, convenient combination, strong practicability, and novel structure.
Structural features:
1. The main electrical performance fully complies with the requirements of IEC60439-1 and GB7251.1;
2. The auxiliary circuit has the functions of local, remote, automatic control and local and remote control switching, and the contactor can heat the relay for protection;
3. The power-receiving main switch has instantaneous tripping and thermal-magnetic tripping protection options. In order to cooperate with the next-level main switch, the instantaneous protection is cancelled, avoiding over-level tripping, and has the functions of self-turning, manual operation and automatic switching;
4. The main switch of the feeder circuit has instantaneous tripping and thermal-magnetic tripping protection. When the user requires it, leakage protection can be installed;
5. The motor control circuit has instantaneous short circuit, overload, undervoltage release and phase failure protection.

Working environment:
1. Temperature: -5~ + 40 ℃, and the average within 24h less than + 35 ℃.
2. Altitude: no more than 2000m.
3. The ambient air temperature, not more than 40℃; at lower temperatures can have a higher relative humidity on (eg: + 20at 90%), taking into account the change in temperature allows the generation of a moderate condensation.
4. Equipment installation and the vertical gradient should do not exceed 5 °
5. Equipment should be installed in the absence of severe vibration, shock-free, and corrosion-free place
6. Note: More than the above conditions can be negotiated with the company.
