PMV40A600 - 3PH SYSTEM PROT. RELAY 600VMULTIFUNCTION

Why Choose the PMV40A600?

The Lovato PMV40A600 is a voltage monitoring relay designed for three-phase systems without neutral. It monitors asymmetry, phase loss and incorrect phase sequence on 600 VAC, 50/60 Hz networks. With a self powered supply and a single relay output, this PMV40 designation device delivers dependable protection and signalling. Programming is via front potentiometers for straightforward on-device adjustment.

Built for reliability, the PMV40 designation offers Ith (IEC) 8 A and a rated impulse withstand voltage of 6 kV. It operates from -20 to +60 °C and has a mechanical life of 30,000,000 cycles. Conformance to IEC/EN 60255-5, IEC/EN 61000-6-2, IEC/EN 61000-6-3, UL 508 and CSA C22.2 n° 14 supports use in compliance-led installations.
