PMV80NA240 - RELE' PROT.RETE 3F/N 208/240V MULTIFUNZ.

Why Choose the PMV80NA240?

Ensure dependable grid protection with the Lovato PMV80NA240 voltage monitoring relay for three-phase systems. The PMV80NA240 supervises minimum and maximum AC voltage and frequency, and identifies phase loss, neutral loss and incorrect phase sequence to safeguard equipment and processes. Designed for networks operating at 208...240VAC 50/60Hz, it supports installations with or without neutral, providing early fault indication and control integration across industrial and commercial power distribution.

Self powered from the monitored supply, this relay simplifies wiring and commissioning. Two relay outputs offer flexible signalling or tripping, while front potentiometers make set-up quick and precise. Built for resilience with 6 kV impulse withstand, -20 to +60 °C operating range and 8 A Ith, it meets IEC/EN 60255-5, 61000-6-2 and 61000-6-3. A robust choice where reliable voltage and frequency supervision is essential.
