This soft starter is suitable for coal mines containing explosive gas (methane) and coal dust. In AC 50Hz, voltage 1140V or 660V, neutral point ungrounded power supply system, perform various forms of soft starting (such as current limit, voltage ramp and power torque ramp for three-phase squirrel cage motors with currents below 200A and 400A) ) . It also has perfect protection function and fault display function, which greatly reduces the troubleshooting time.

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).

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 380V, ungrounded three- phase center. To control the forward and reverse rotating of three-phase asynchronous motor.

The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit center. To local control or remote control the start and stop of AC 50Hz, voltage 1140V, 660V or 380V, ungrounded three- phase asynchronous motor, and can be reversed at the stop.

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.
