QBZ-20012080/1140(660380)N, BQD-120(80)N/660(380) Mine explosion-proof reversible vacuum electromagnetic starter
A. Purposes
QBZ-200, 120, 80/1140(660, 380)N, BQD-120(80)N/660(380) mine explosion-proof reversible vacuum electromagnetic starter is ideal for use in AC 50Hz, rated voltage≤ 1140V power supply network without neutral line directly grounded, in coal mines with methane compound gases and dangerous explosive gases for remote control on 3-phase squirrel cage asynchronous motors.
B. Protective functions
1. Rated current can be modified and adjusted by code-dialing switch and
Range switch;
2. The starter has protective functions of short-circuit, overload, phase loss,
Overvoltage and current leakage etc;
3. Remote control on forward and reverse rotation.
