Carlo Gavazzi DPB02CM48 3 Phase Monitoring Relay, Phase Loss, Sequence and Asymmetry, 380 to 480 VAC

The Carlo Gavazzi DPB02CM48 is a 3 phase monitoring relay that detects phase loss, incorrect phase sequence and voltage asymmetry. The asymmetry limit and alarm delay are set on front dials, and nominal voltage and mains type are selected by DIP switch, so one relay suits both 3 wire and 4 wire systems. It is powered from the monitored phases and also detects regenerated voltage.
