PMV30A600 - 3PH SYSTEM MULTIF. PROTECTION RELAY 600V

Why Choose the PMV30A600?

Lovato PMV30A600 is a robust voltage monitoring relay for three‑phase systems without neutral, engineered to safeguard equipment from supply anomalies. Monitoring at 600 VAC 50/60 Hz, it detects minimum AC voltage, phase loss and incorrect phase sequence. The device is self powered from the line and provides a single relay output for signalling or control, with straightforward adjustment via potentiometers for quick commissioning in industrial panels.

Built on Lovato’s PMV30 platform, the relay combines long mechanical life of 30,000,000 cycles with a 6 kV impulse withstand capability for resilient performance. It operates reliably from -20 to +60 °C and conforms to IEC/EN 60255-5, 61000-6-2/-6-3, UL 508 and CSA C22.2 n° 14. With Ith (IEC) 8 A and 0.8 Nm max terminal torque, it supports demanding control applications.
