PMV70A575 - 3 PHASE LINE VOLTAGE CONTROL RELAY PMV70

Why Choose the PMV70A575?

Ensure safe, reliable mains control in demanding three‑phase installations with the Lovato PMV70A575 voltage monitoring relay. The PMV70A575 monitors 380…575VAC (50/60Hz) systems without neutral, detecting minimum and maximum voltage, asymmetry, phase loss and incorrect phase sequence. With self‑powered operation and a single relay output, it provides straightforward protection signalling for panels and machinery requiring dependable supply condition supervision.

Setpoints and behaviour are configured via potentiometers for quick commissioning and repeatable results. Built for industrial environments, it features 8 A Ith, 6 kV impulse withstand and a -20 to +60 °C operating range, with 30,000,000 mechanical cycles. Compliance with IEC/EN 60255-5, IEC/EN 61000-6-2/-6-3, UL 508 and CSA C22.2 n° 14 supports use across regulated applications.
