DPB01CM23N is a DIN-rail mounted, 3-phase voltage monitoring relay for 3P+N systems, detecting phase loss and providing overvoltage and undervoltage protection without phase sequence detection. It operates from 208 to 240 VAC ±15% (177 to 276 VAC), supports 50 to 60 Hz mains frequency, and derives power from the monitored lines. Adjustable setpoints for overvoltage and undervoltage are controlled via front dials, with alarm delay up to 30 seconds. It features a changeover relay output rated at 8 A at 250 VAC, with status LEDs for ON and alarm indication. A selectable 1 s or 6 s power-on delay prevents nuisance tripping during startup. The device has basic insulation between terminals and 2.5 kVrms isolation between input and output. Power consumption is under 2.5 VA.
