PMV50NA600 - PROTECTION RELAY 3P+N 480/600V MULTIFUNCTION

Why Choose the PMV50NA600?

Lovato PMV50NA600 voltage monitoring relay safeguards three‑phase systems with or without neutral, ensuring dependable supervision across 480 to 600 VAC at 50/60 Hz. It monitors minimum and maximum AC voltage and detects phase loss, neutral loss and incorrect phase sequence to help protect downstream equipment. Self powered with two relay outputs, the PMV50NA600 delivers reliable signalling and control for panels that need accurate voltage and phase condition monitoring.

Setpoints are easily adjusted via potentiometers, streamlining commissioning and maintenance. Built on the PMV50N designation, it offers Ith 8 A, 6 kV impulse withstand, and a −20 to +60 °C operating range, with a mechanical life of 30,000,000 cycles. Conformity with IEC/EN 60255-5, 61000-6-2 and 61000-6-3 underpins performance in industrial environments while the compact 200 g design supports straightforward panel integration.
