PGR-6150 Motor Protection System
PGR-6150-OPI Operator Interface
Functions:
- Modular system that provides integrated protection, metering and data logging functions
- The PGR-6150 base module can operate as a stand-alone unit or with the PGR-6150-OPI Operator Interface
- PTC temperature input to provide overtemperature protection
Features:
- Integrated current transformers (CTs) suitable for motor currents up to 25 A; external CTs can be used to work with large motors
- Thirteen current- and temperature-based protective functions to prolong the life of three-phase motors
- Calculated and measured definite- and inverse-time ground-fault protection
- Four programmable LED fault indicators on the base module, six on the operator interface
- Fail-safe (undervoltage) operating mode
- Standard RS-485 (Modbus RTU) network communications
- Optional 40-character display provides access to online metering, data logs, and programming changes
- DIN-rail mounting
- Five year warranty

Typical Applications:
- Used on low-voltage motors for conveyors, ventilation fans, and other applications that require multiple protection features
Minimum System Components:
The PGR-6150 does not require phase CTs for motors with full-load currents of 25 A or less. External phase CTs are available for large motors. An optional PGR-6150-OPI Operator Interface can be used for metering, data log access, and programming. The PGR-6150 can be programmed directly through the PGW-6150 Relay Interface Software.

Operator Interface
An optional 40-character LCD display with 6 user-programmable LEDs for programming and viewing PGR-6150 metered data. Comes with 1 m cable.
