PMV70A600 - 3 PHASE LINE VOLTAGE CONTROL RELAY 600V

Why Choose the PMV70A600?

Lovato PMV70A600 voltage monitoring relays provide reliable protection for three-phase systems without neutral at 600VAC, 50/60Hz. The SKU PMV70A600 monitors minimum and maximum AC voltage and phase asymmetry, and detects phase loss and incorrect phase sequence to help prevent equipment damage. With a self-powered design and a single relay output, this PMV70 series unit offers straightforward control integration for critical plant, panels and machinery.

Engineered for industrial resilience, the PMV70 features potentiometer programming for quick setup, 6 kV impulse withstand, and -20 to +60 °C operating range. A robust 30,000,000-cycle mechanical life, 8 A Ith per IEC, and secure 0.8 Nm terminal tightening add durability and reliability. Conformity with IEC/EN 60255-5, 61000-6-2, 61000-6-3, plus UL 508 and CSA C22.2 n° 14 supports broad compliance requirements.
