PGR-6800 Pump Protection Relay
Functions:
- Provides advanced overload protection for three-phase pumps up to 1,000 Vac
- Current unbalance protection to guard against excessive heating
- Undercurrent protection to detect a no-load or dry-running condition
Features:
- Integrated current transformers (CTs) suitable for motor currents up to 91 A; external CTs can be used to work with large motors
- Dependable overload protection
- Selectable undercurrent trip level from 50 to 90%
- Self-test function
- Fail-safe (undervoltage) operating mode
- Remote reset and indication using PGB-6800
- DIN-rail mounting
- Five year warranty

Typical Applications:
- Used on low-voltage pumps for pumpjacks, water and wastewater treatment, and other submersible pumping applications
- For advanced overload applications where temperature protection is required, see the PGR-6130 Electronic Overload Relay
Minimum System Components:
The PGR-6800 does not require phase CTs for motors with full-load currents of 91 A or less. External phase CTs are available for large motors.
