PMV70A240 - 3 PHASE LINE VOLTAGE CONTROL RELAY PMV70

Why Choose the PMV70A240?

Lovato PMV70A240 is a voltage monitoring relay for three‑phase systems without neutral, safeguarding equipment on 208…240VAC 50/60Hz supplies. It supervises minimum and maximum AC voltage and asymmetry, and detects phase loss and incorrect phase sequence. With self powered operation and one relay output, it delivers dependable protection across industrial panels. Setup is straightforward via potentiometers for on-site adjustment.

Engineered to perform in demanding environments, the PMV70 series device offers Ith (IEC) 8 A, rated impulse withstand Uimp 6 kV and a wide operating temperature from −20 to +60 °C. It complies with IEC/EN 60255-5, 61000-6-2, 61000-6-3 and carries UL 508 and CSA C22.2 n° 14 references, with sustainability certification. Product type designation: PMV70; weight 130 g; maximum terminal tightening torque 0.8 Nm.
