Earth-leakage monitoring relay PGR-6101-120

insulation2 NO/NCthree-phase

The PGR-6101 series relay operates on one- or three-phase solidly grounded, resistance-grounded, and ungrounded ac systems up to 6 kV. This relay combines the features of a ground-fault protection relay and insulation monitor into one unit. It protects against ground-faults by monitoring insulation resistance when the motor is de-energized and by monitoring ground-fault current when the motor is energized. The PGR-6101 features two separate analog outputs for optional current and ohm meters as well as two separate alarm relays. Features • Adjustable GF pickup (30–200 mA) • Adjustable insulation pickup (60–600 kΩ) • Adjustable time delay (50–250 ms) • Output contacts • Analog outputs (0–1 mA) • CT-loop monitoring • Selectable contact operating mode • POWR-GARD® technology
