Carlo Gavazzi DPA01CM44 Relay

Carlo Gavazzi DPA01CM44 is a dedicated 3-phase loss- and sequence-monitoring relay with regenerated voltage detection that mounts on a standard 22.5 mm DIN-rail and continuously checks all three phases for presence and correct order, triggering the relay when an imbalance or mis-sequencing could jeopardize motor or equipment safety. The device covers a broad AC voltage spectrum with a nominal range of 208–480 VAC and provides four selectable sub-ranges—208–240 VAC, 208–480 VAC, 380–480 VAC, and 440–480 VAC—along with a 50–60 Hz operating frequency and a single SPDT relay output, with no adjustable time delay. Designed for industrial environments, it carries CE, CSA, and CCC certifications, mounts via DIN rail, and lists E-numbers 4367529 (NO) and 3864690 (SE); setting method via NFC is not available. This model is part of Carlo Gavazzi’s DPA01 family and is intended for reliable phase monitoring in automation and protection schemes, making it suitable for protecting motors, pumps, and other three-phase loads where maintaining correct phase presence and sequencing is critical.
