QJZ Vacuum Electromagnetic Starter Introduction
QJZ series mining explosion-proof and intrinsically safe vacuum electromagnetic starter is mainly suitable for the coal mine, as a long distance or direct control of ac 50 hz, voltage 1140 v mining flame-proof three-phase squirrel-cage asynchronous motor start and stop. And when to stop, to change the control power of the motor phase operation..Starters with overload, phase failure, short circuit, over-voltage leakage blocking and absorbing protection, the starter can achieve a single remote control, local control, dual interlock control as well as multiple starters positive sequence starting.
