Why Choose the Lovato PMV80NA600 Voltage Monitoring Relay?
The Lovato PMV80NA600 is a multifunction three-phase voltage monitoring relay designed to protect electrical installations against abnormal supply conditions. Suitable for 480 to 600 V AC 50/60 Hz systems with or without neutral, it continuously monitors voltage, frequency and phase conditions to help prevent costly equipment damage and unexpected downtime.
As part of the trusted Lovato PMV80N series, this relay combines under and overvoltage protection, under and overfrequency monitoring, phase loss detection, neutral loss detection and incorrect phase sequence monitoring within a compact DIN rail mounted unit. Adjustable settings allow engineers to tailor protection levels for demanding industrial environments.
With dual SPDT relay outputs, automatic reset functionality and user-friendly potentiometer adjustment, the PMV80NA600 offers dependable protection for motors, pumps, compressors, switchboards, generators and industrial power distribution systems where reliable three-phase monitoring is essential.
