The PGR-3200 detects ground faults by continuously monitoring the insulation integrity of ungrounded electrical systems. The relay monitors the insulation for damage and assists with predictive maintenance and troubleshooting of developing ground faults by providing two warning and an alarm level. The PGR-3200 operates on one- or three-phase ungrounded systems up to 6 kV.

The PGR-3200 can also be used on a grounded system to monitor the insulation for damage, while the power system is de-energized. The mode-of-operation terminals (27-28) are connected to the circuit breaker or contactor auxiliary contacts to toggle the relay off when the contactor or breaker is closed.

Features & Benefits:

 

• NEC® and CEC Code compliant: Meets National Electrical Code (NEC®) Article 250.21(B) and Canadian Electrical Code Part 1, Section 10-106 (2) requirements for ungrounded systems
• Output contact (50 kΩ): Form C output contact for alarming when the insulation resistance is below 50 kΩ
• Output contact (10 kΩ): Form C output contact for tripping when the insulation resistance is below 10 kΩ
• Analog output (0-1 mA): Provides means for connecting to an optional meter (PGA-0510) or control system
• DIN-rail or surface: mount Flexible options for ease of installation
