DW80-200,350 Mining explosion-proof feed switchDetailed product description：

Scope and Application
DW80-200、 The 350 mine explosion-proof feeder switch is mainly used in coal mines underground. In AC 50Hz, voltage of 380V or 660V, and current up to 200A or 350A lines, it serves as the main switch and branch switch of the power supply system, and can also be used as a motor for infrequent start-up. When overload or short circuit faults occur in the circuit, the feed switch can automatically cut off the circuit according to requirements, and at the same time, the feed switch can cooperate with the leak detection relay to protect against leakage faults in the system.
