Carlo Gavazzi DPA01DM48 Three Phase Monitoring Relay

Carlo Gavazzi DPA01DM48 is a true RMS 3-phase mains monitoring relay designed to guard 380–480 VAC networks by detecting phase loss and incorrect phase sequence. The device provides two Form C (DPDT) relay outputs, enabling separate control of alarms and interlocks, and it includes regenerated voltage detection to flag faults even while motors are running. This DIN-rail mounted unit is 22.5 mm wide, intended for industrial panels, and operates on 50–60 Hz with power drawn from the monitored mains. Time delay is not adjustable on this model, and setting method through NFC is not available. The DPA01DM48 carries European, North American, and Chinese approvals and is suitable for motor protection, HVAC equipment, pumps, and other three-phase drive applications where reliable phase presence and correct sequence are critical. Its robust 3P monitoring capability targets both phase loss and phase sequence, delivering dependable switching via two DPDT contacts while preserving a compact footprint for retrofits in existing control systems.
