1.Applications
QJX2 series star delta reduced voltage starter is suitable for starting 3-phase squirrel-cage motorin the circuit of AC 50/60Hz, under AC3 utilization category, rated operational voltage 660V andcontrollable power 80W. And it can be used to control start motor stator windings, which changeovelstart, run and stop from “wye” to “Delta Type”, lf used with corresponding thermal overload relay.it will realize the function of overload and phase-failure protection for electric motor.This product is not suitable for reversible change and AC-4 Utilization categoryThis product conformms to GB14048.4、IEC60947-4-1 standard.
