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

The PRRL-200 is a phase loss and reversal relay for three-phase load circuits, rated for 208VAC to 240VAC, with a DPDT output contact configuration and 7 Amps at 240VAC switching capacity. It mounts on a surface with screw terminals and includes a dust cover. The relay operates within 0°C to 40°C and stores between -10°C and 85°C. It detects phase loss at 18% voltage drop and de-energizes upon phase reversal, with fixed 5-second pick-up and drop-out delays. Power consumption is 16VA. The unit has approximate dimensions of 4.25" x 3.75" x 2.75" and weighs 8 ounces.
