PMV50NA240 - PROTECTION RELAY 3P+N 208/240V MULTIFUNCTION

Why Choose the PMV50NA240?

Ensure reliable mains supervision with the Lovato PMV50NA240 voltage monitoring relay. Designed for three-phase systems with or without neutral, it safeguards equipment against minimum and maximum AC voltage issues, phase loss, neutral loss and incorrect phase sequence. The PMV50NA240 is self powered and offers two relay outputs for flexible signalling or control, making it a dependable choice for industrial panels and building services where uptime and protection matter.

Installation and configuration are straightforward using on-unit potentiometers, while a mechanical life of 30,000,000 cycles and a 6 kV impulse withstand support harsh environments. Operating from -20 to +60 °C and conforming to IEC/EN 60255-5, 61000-6-2 and 61000-6-3, this relay integrates smoothly into control panels. Rated at 8 A Ith and 208...240VAC 50/60Hz, it delivers consistent protection across varied applications.
