Qbz-120/660 (380) Mining Explosion Proof Type Vacuum Electromagnetic Starter

QBZ-120/660(380)(II) Mining Explosion-proof Starter/ Vacuum Electromagnetic Starter

Function

This series mining explosion-proof type vacuum electromagnetic starter is applicable in AC 50Hz distribution system of three-phase indirect neutral-point earthing with rated voltage of 1140, 660V or 380V in underground coal mines with explosive and dangerous gas (methane) and coal dust, it is used to control direct start, stop and reversal of three-phase squirrel-cage asynchronous motor with rated current of 200A, 120A, 80A. Meanwhile, it also dose protection to motor and relative circuit.

Character

It adopts dialing and lever combined and setting, which can modify and set rated current;

Various protective functions like overload, short circuit, under voltage, over voltage, loss of phase, leakage lockout, phase unbalance etc.
