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

The PRR-O-200 is a phase loss and reversal relay designed for 208VAC to 240VAC, 3Ø applications, with a surface mount, screw terminal connection, and SPDT output contacts rated at 7 amps at 240VAC. It operates within a temperature range of 0°C to 40°C and features fixed 5-second pick-up and drop-out delays for phase loss detection. The relay de-energizes upon phase reversal or a 18% voltage drop in any phase and consumes 16VA. It has a mechanical life of 10,000,000 cycles and an electrical life of 100,000 full-load cycles. Mounting is surface-only, with a dust cover for environmental protection, and the unit weighs approximately 8 ounces.
