PMV30A240 - 3PH SYSTEM MULTIFUNCTION PROTECTION RE

Why Choose the PMV30A240?

Lovato PMV30A240 is a voltage monitoring relay for three-phase systems without neutral, providing minimum AC voltage supervision alongside phase loss and incorrect phase sequence detection. Operating at 208...240VAC, 50/60Hz and self powered from the monitored supply, it is set via potentiometers. Part of the PMV30 range, it offers a single relay output for straightforward integration in protection and control schemes.

Engineered for durability, the relay offers a mechanical life of 3,000,000 cycles and Ith (IEC) of 8 A, with a rated impulse withstand voltage of 6 kV. It operates from -20 to +60 °C and stores from -30 to +80 °C. A maximum terminal tightening torque of 0.8 Nm and 130 g weight aid practical installation. Conformity includes IEC/EN 60255-5, IEC/EN 61000-6-2, IEC/EN 61000-6-3, UL 508 and CSA C22.2 n° 14.
