Purpose

QJZ-400(315,200)/1140(660)explosion-proof and intrinsically safe vaccum electromagnetic starter is suitable to the mine well with mixed gas containing methane.

In the power supply system of 50 Hz AC, rated voltage of 1140 V and below and the triphase neutral not grounding, the product can control triphase squirrel cage asynchronous motor .

Technical features

1)    With the indication of closing, opening of starter ,on-line status and kinds of faults;

2)    Rated current can be adjusted by code-dialing  on motor synthetical protector ;

3)    With the protective functions of short circuit, over load, loose phase, current leakage interlock;

4)    With function of  interlinked control.
