Low voltage withdrawable switchgear is a type of low-voltage distribution equipment suitable for AC 50Hz, rated voltage 380V (660V), and rated current up to 3150A. It is widely used in power distribution systems of industrial and mining enterprises, public facilities, and high-rise buildings. The equipment adopts a modular design, and the functional units can be flexibly extracted for easy installation, maintenance, and expansion. At the same time, it has protection functions such as overload, short circuit, and leakage. Its compact structure, reliable performance, and ability to adapt to complex operating environments provide users with safe and efficient power distribution solutions
