DESCRIPTION

The DPC02DM23 is a true RMS three-phase monitoring relay designed to detect phase loss, incorrect phase sequence, over/under voltage, and over/under frequency conditions in electrical systems. It features separately adjustable setpoints for voltage and frequency monitoring, with independently configurable delay functions ranging from 0.1 to 30 seconds. The relay provides two 8 A SPDT relay outputs rated at 250 VAC, with mechanical life exceeding 30 million operations and electrical life of at least 100,000 operations at rated load. The device operates on a supply range of 208 to 240 VAC (M23 variant) with a measuring voltage range of 177 to 275 VAC, and includes LED indicators for power supply, alarm status, and relay operation. Housed in a 45 mm Euronorm DIN-rail mount enclosure with IP 20 protection, the DPC02DM23 is commonly used in generator set monitoring, mains protection systems, and industrial power distribution applications where reliable three-phase system supervision is critical.
