Carlo Gavazzi DPA51CM44 – Phase Sequence & Phase Loss Monitoring Relay

Carlo Gavazzi DPA51CM44 – Phase Sequence & Phase Loss Monitoring Relay

The Carlo Gavazzi DPA51CM44 is a monitoring relay for three-phase systems, engineered to detect incorrect phase sequence and phase loss. It operates using its own 3-phase supply, with detection tolerance for regenerated voltages up to 85% of nominal. This compact DIN-rail unit provides reliable protection and clear LED indication for power and alarm status.
