The PGR-6101 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, and two separate alarm relays. It operates on one- or three-phase solidly grounded, resistance grounded and ungrounded systems up to 6 kV.

Features & Benefits:

 

• Adjustable GF pickup (30-200 mA): Trip setting provides a wide range of low-level protection and system coordination
• Adjustable insulation pickup (60-600 kΩ ): Customizable insulation resistance setpoints for maximum protection
• Adjustable time delay (50-250 ms ): Adjustable trip delay for quick protection and system coordination
• Output contacts: Two Form C output contacts for ground fault and insulation-resistance fault
• Analog outputs (0-1 mA): Two analog outputs indicate insulation resistance and ground-fault current
• CT-Loop monitoring: Alarms when CT is not connected
• Selectable contact operating mode: Selectable fail-safe or non-fail-safe operating modes allows connection to shunt or undervoltage breaker coil
