The SELEC VPRA2M-CE Protection Relay is a highly reliable and precise three-phase analog voltage protection device designed for industrial and commercial electrical systems operating at 230VAC. It offers comprehensive monitoring and protection against electrical anomalies such as overvoltage, undervoltage, phase asymmetry, phase sequence errors, phase failure, and neutral loss. This relay operates efficiently within a supply voltage range of 127 to 288V AC (L-N), making it ideal for 220V single-phase (L-N) and three-phase configurations (3Ø-4W). Featuring a rugged 35mm DIN rail mount design and a user-friendly LED indication system, the VPRA2M-CE enables quick fault detection and troubleshooting, minimizing downtime. The device incorporates configurable trip time delays (0-15 seconds), power-on delays (0-15 seconds), and a fixed recovery delay (5 seconds ± 200 ms) to tailor protection responses to specific system requirements. The accuracy of trip settings is maintained within ±5%, while the time settings have an accuracy of ±10%, ensuring reliable and precise protection. The relay’s output includes two changeover (DPDT) contacts rated at 5A for both NO and NC at 250V AC / 28V DC, allowing seamless integration with control circuits and alarm systems. Crafted for use in demanding industrial environments, this protection relay safeguards electrical installations against voltage irregularities, ensuring operational continuity and equipment longevity.
