Low Voltage Switchgear

Low-voltage switchgear is an integrated unit consisting of one or more low-voltage switching devices combined with control, measurement, and protection components, with all electrical and mechanical connections completed at the factory and assembled using structural components. With a rated voltage of ≤1000 V AC and ≤1500 V DC, it serves as a critical link in power systems connecting the low-voltage side of transformers to end-use loads. The core standard is IEC 61439. Based on installation method, they are classified as fixed-type and withdrawable-type. Their primary functions include power distribution, circuit protection, control and monitoring, and reactive power compensation. They are suitable for various building electrical applications, including industrial, residential, and government infrastructure sectors.
