The WPM-VMR-3PH-PH is a 3-phase voltage monitoring relay with a single relay output for alarm on phase error. It measures 58 mm deep, 22.5 mm wide, and 90 mm long, and mounts on a TS 35 rail. It monitors 400 V AC (L-L) ±15% at 40-60 Hz and switches a 3 A, 250 V AC / 24 V DC relay contact with a response time of ≤200 ms. Galvanic isolation of 2 kV DC / 1 min separates input, output, and supply. Operating temperature ranges from -40 °C to 60 °C. It complies with RoHS with exemption 7cI, meets IEC 61000-6-2 and IEC 61000-6-4 EMC standards, and has an IP20 protection rating. Connection is via screw terminals for 0.5-2 mm² wire with a torque of 0.4-0.6 Nm.
