PMV30A575 - 3PH SYSTEM MULTIFUNCTION PRO- TECTION RE

Why Choose the PMV30A575?

The Lovato PMV30A575 voltage monitoring relay safeguards three-phase systems without neutral by supervising minimum AC voltage and detecting phase loss and incorrect phase sequence. Covering 380…575 VAC at 50/60 Hz, this self‑powered unit integrates simply into control panels and offers one relay output for dependable signalling. Setup is straightforward via front‑panel potentiometers, reducing commissioning time while maintaining precise protection thresholds.

Engineered for longevity and resilience, the PMV30 series device delivers 3,000,000 mechanical operations, 8 A Ith (IEC) and 6 kV impulse withstand capability. It operates from −20 to +60 °C and stores from −30 to +80 °C, with secure terminals rated to 0.8 Nm. Conformity to IEC/EN 60255-5, 61000-6-2/-6-3, UL 508 and CSA C22.2 n° 14 supports compliance in global panels.
