Carlo Gavazzi DPA01CM44 3 Phase Monitoring Relay, Phase Loss and Sequence, 22.5 mm DIN Rail

The Carlo Gavazzi DPA01CM44 is a 3 phase monitoring relay that protects motors, pumps and machines from phase loss and incorrect phase sequence. The relay operates only when all three phases are present and in the correct sequence, so equipment cannot start or keep running on a faulty supply. It also detects regenerated voltage, and is powered from the monitored phases, so no separate supply is needed.
