DESCRIPTION
DPB51CM44 is a multifunction true RMS 3-phase mains monitoring relay designed for monitoring phase loss, phase sequence, overvoltage, and undervoltage conditions. It operates on both 3P and 3P+N systems with a wide voltage range of 208 to 480 VAC at 50-60 Hz, with power supply provided by the monitored mains. The relay features front dial adjustable overvoltage and undervoltage setpoints (2 to 22%), adjustable alarm delay time from 0.1 to 30 seconds, and a SPDT changeover relay output rated at 5 A @ 250 VAC. Housed in a compact 17.5 mm wide DIN-rail enclosure with dimensions of 17.5 x 90 x 67.2 mm, it offers ultra-high harmonic immunity and operates in temperatures from -20 to 60°C. This relay is ideal for power plants, substations, and industrial applications requiring reliable 3-phase voltage monitoring and protection.
