PGR-6803-240规格书详情
Description
The PGR-6800 Pump Protection Relay provides protection for
pumps with three-phase motors up to 1,000 Vac. No current
transformers are required for currents up to 91 A. The protective
functions include overload, phase unbalance, phase loss, phase
sequence and undercurrent. The PGR-6800 Pump Protection
Relay is ideally suited for applications where operating without
load can induce failure. Motor current is monitored and an
undercurrent trip occurs when the current drops below a
preset level. No additional level detectors are required.
