PMV20A600 - PHASE SEQUENCE/PHASE LOSS MODULAR RELAY

Why Choose the PMV20A600?

Lovato’s PMV20A600 voltage monitoring relay safeguards three-phase systems without neutral, detecting phase loss and incorrect phase sequence to prevent equipment damage. Self powered from the monitored supply, it supervises 380–600 VAC at 50/60 Hz with a single relay output for straightforward integration. As part of the PMV20 range, it delivers reliable protection for panels and OEM builds.

Engineered for demanding environments, the PMV20A600 offers 6 kV impulse withstand (Uimp), 8 A Ith, and a mechanical life of 3,000,000 cycles. It operates from -20 to +60 °C and meets IEC/EN 60255-5, IEC/EN 61000-6-2/-6-3, UL 508 and CSA C22.2 n° 14. A compact, lightweight 120 g design and secure 0.8 Nm terminals support dependable installation.
