The Phase Monitoring Relay is designed to monitor single- or three-phase over- and undervoltage, neutral monitoring, and phase loss. It has a neutral connection and operates within a measuring range of (L-L) 320-460 VAC and (L-N) 185-265 VAC. The relay can be powered by a rated control supply voltage of (L-L) 320-460 VAC or (L-N) 185-265 VAC. Additionally, it features two normally open (NO) outputs.
