 Product Information
This series mining explosion-proof and intrinsically safe type vacuum electromagenetic starter is applicable in AC 50Hz distribution sysetm with rated voltage of 1140V or 660V in underground coal mines with explosive and dangerous gas(methane) and coal dust,it is used to control the direct start and stop and reversal of three-phase squirrel-cage asynchronous motor with rated current of 400A,315A and 200A,meanwhile, it also does protection to motor and relative circuit.The starter can be connnected with methane power-off instrument,where it is overrun,the starter will switching off to realize power off.
