The PRRO-200 is a phase loss and reversal relay for 208VAC to 240VAC, 3-phase systems, mounted on a surface with screw terminals and a dust cover. It features an SPDT output contact rated at 7 Amps at 240VAC, with 100,000 electrical cycles and 10,000,000 mechanical cycles. The relay de-energizes if phase rotation is reversed or if any phase loses 18% or more voltage. It operates from 0°C to 40°C, consumes 16VA, and has fixed 5-second pick-up and drop-out delays. The unit weighs approximately 8 oz. and is listed to 42L2.
