Application

Used in coal mine or underground where exists methane compound gases and dangerous explosive gases, applys for AC50HZ, 1140V and 660V and 380V circuit. With the explosive-proof button can near-control or remote-control start-stop, complete meet the logical relationship between oil pump motor and main motor start, including main motor rotates forward or backforward. The start has the protection of overload, phase-lose, short circuit, leakage atresia, under-pressure, voltage-absorption, making a full protective function.
