The ARB series is a duplex relay designed to alternate between two loads to equalize runtime, with a three-position field-selectable switch for normal duplexing or locking into A-B or B-A sequence. It operates on control voltages of 24, 120 VAC/DC, 208, or 240 VAC at 50/60 Hz, requires approximately 3 VA, and features LED indicators showing output position. The relay has SPDT contacts rated at 10 A at 240 VAC resistive, 1/8 hp at 120 VAC, or 1/4 hp at 240 VAC inductive, and 360 VA inductive. Enclosure is a Lexan™ dust cover with industrial plug-in terminations. Mechanical life is 10 million operations minimum; electrical life is 100,000 operations at rated load. Operating temperature range is -20°C to +55°C, storage temperature is -40°C to +85°C.
