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

PVCL-200-AR is a three-phase voltage relay designed to monitor line voltage, phase rotation, phase imbalance, and phase loss in 208VAC to 240VAC, 3Ø systems. It features screw terminals, surface mounting, and a dust cover, with physical dimensions of 4.25 in. length, 3.75 in. height, and 2.75 in. depth, weighing approximately 8 oz. The relay has SPDT or DPDT output contacts rated for 7 A at 120 VAC and 5 A at 240 VAC, supporting 100,000 electrical cycles and 10,000,000 mechanical cycles. It operates within temperatures from -20°C to 40°C and includes a fixed 5-second pick-up and drop-out delay. Automatic reset functionality is provided, and the output de-energizes if voltage deviates by more than 10% from the setpoint, phase imbalance exceeds 5%, or phase loss occurs.
