Description

The PGR-6130 Electronic Overload Relay provides protection
for small three-phase motors up to 1,000 Vac. No current
transformers are required for currents up to 91 A. The
protective functions include overload, overtemperature, phase
unbalance, phase loss, and phase sequence. The PGR-6130
Electronic Overload Relay offers dependable protection and can
be used on pumps, conveyor belts, ventilation fans and other
small-motor applications that require standard protection.
