Carlo Gavazzi DPA Three-Phase Monitoring Relays are designed for the detection of incorrect phase sequence and total and partial phase loss. These relays feature a supply range from 208VAC to 690VAC that is covered by two multi-voltage relays. Carlo Gavazzi DPA Three-Phase Monitoring Relays are capable of detecting regenerated voltages up to 85% of the nominal voltage (phase-phase). These relays are available in a 22.5mm Euronorm housing (DPA01) or in a 36mm plug-in module (PPA01).
