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.
