R-K Electronics, Inc. Protection Relays & Systems PRRL-600

The PRRL-600 is a phase loss and reversal relay for three-phase systems, rated for 575VAC to 600VAC input. It features a DPDT output contact configuration, screw terminals, and surface mounting. The relay operates within 0°C to 40°C ambient temperatures and has a power consumption of 16VA. It detects phase loss at 18% voltage drop and phase reversal, de-energizing the output under fault conditions. The device is rated for 100,000 full load electrical cycles and 10,000,000 mechanical cycles, with a contact rating of 5A at 240VAC. It includes a dust cover and weighs approximately 8 oz. The relay is listed to 42L2 standards.
