BKD11-400Z/660(380) Mining Explosion proof Vacuum Feed SwitchDetailed product description：

Scope and Application

The BKD11-400Z feeder switch is suitable for use in environments with explosive mixtures of gases such as methane and coal dust in coal mines and their surrounding media. It can be used as the main or branch switch of the power supply system in circuits with AC 50Hz, rated voltage of 660V or 380V, and rated current up to 400A. It can also be used as a high-capacity motor for infrequent start-up. The feed switch has overload protection, remote and near end short circuit protection, voltage loss protection, selective leakage protection, as well as short circuit and leakage test functions. The branch switch also has the functions of leakage lockout protection and self recovery after leakage tripping.
