The soft starter is suitable for coal mines containing explosive gas (methane) and coal dust.In an AC 50Hz, voltage 1140V or 660V, neutral ungrounded power supply system, various forms of soft start (such as current clipping, voltage ramp and power torque ramp) are performed on three-phase squirrel-cage motors with currents up to 200A and 400A.The controller also has the perfect protection function and the fault display function, greatly reduces the time of troubleshooting.

Mining explosion-proof and intrinsically safe low voltage AC soft starter (hereinafter referred to as starter) is suitable for mine containing explosive dangerous gas and coal dust. in AC 50Hz, rated voltage AC1140V (660V) power supply system, four three-phase squirrel cage motors with current below 400A can be started in many forms (such as current limiting, voltage slope and power torque slope).

This product is suitable for an environment with coal mine gas, coal dust, and other explosive gases underground, to logically control the start, stop and double-speed of the three-phase AC asynchronous motor or AC double-winding motor in the circuit of AV 1140V or 660V. And it has a joint control function.

The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit of AC 50Hz, voltage 660V or 1140V, ungrounded three-phase center. To local control or remote control the start and stop of three-phase asynchronous motor, and can be reversed at the stop.
