Rated Voltage: The rated voltage of XL-21 power cabinet covers multiple common industrial voltage grades, such as 380V, 400V, 660V, etc. It can be selected and configured according to different power consumption requirements and power supply systems to meet the normal operation of various industrial equipment.
Rated Current: It features a wide rated current range from several hundred amperes to several thousand amperes. For instance, common small XL-21 power cabinets have a rated current of around 400A-630A, suitable for power distribution of basic electrical equipment in small factory workshops or commercial premises. Large XL-21 power cabinets can reach 1600A, 2000A or even higher, mainly applied in fields with high power demand such as large industrial enterprises, mines and metallurgy. They can carry and distribute heavy current to ensure stable power supply for high-power electrical equipment.
Short-time Withstand Current: It has a certain short-circuit withstand capacity, generally at the level of tens of kiloamperes. This indicator is critical. In case of a short-circuit fault in the circuit, the power cabinet can withstand the impact of short-circuit current for a short time without damage. Its internal short-circuit protection devices (e.g. circuit breakers) will quickly disconnect the faulty circuit, preventing further damage to other equipment in the electrical system and safeguarding the safety of personnel and devices.
