PGR-6200 SERIES
Motor Protection Relay
Description
The PGR-6200 Motor Protection Relay offers enhanced
motor protection and metering to provide diagnostic and
troubleshooting capabilities for critical process motors. The
PGR-6200 is used to provide current- and temperature-based
protection, metering, and data logging for three-phase lowvoltage medium-horsepower induction motors. This relay is
ideal for retrofitting and upgrading motor protection using
existing CTs. See the PGK Family of Panel Mount Adapter Kits
to replace common obsolete relays.
