R-K Electronics, Inc. Protection Relays & Systems PVC-200-AR

The PVC-200-AR is a three-phase voltage relay designed for monitoring and protecting electrical systems. It features a 10 Amp output relay with one normally open (NO) and one single pole double throw (SPDT) contact. The relay is capable of detecting undervoltage, phase loss, phase imbalance, and phase rotation, ensuring that all phases are present and balanced within specified tolerances. The device operates within a line voltage range of 208VAC to 240VAC and is suitable for 3-phase systems. It includes a fixed 5-second pick-up delay to allow for stabilization of the line voltage and a similar drop-out delay to prevent nuisance tripping. The PVC-200-AR can handle a maximum overvoltage of 10% above the nominal voltage and is designed to operate in ambient temperatures ranging from -20¬8C to 40¬8C. With a power consumption of 16VA, the relay is rated for 100,000 full load electrical cycles and 10,000,000 mechanical cycles, indicating a robust design for long-term reliability. The PVC-200-AR is mounted on a surface and features screw terminal connections, making installation straightforward. This product is suitable for applications requiring reliable voltage monitoring and protection in three-phase electrical systems.
