R-K Electronics, Inc. Protection Relays & Systems CSRA-115A-1-5-AR

CSRA-115A-1-5-AR is an adjustable AC current sensing relay with automatic reset, designed for motor protection by detecting overcurrent or undercurrent conditions. It operates from a 115 VAC supply and senses current in the fixed 1 to 5 A range. The relay has a 0.525-inch diameter thru-hole for conductor passage, terminates with a terminal block compatible with up to 12 AWG wire, and supports surface or DIN rail mounting. Its power consumption is 6 VA, it withstands 100,000 electrical cycles at 7 A, 120 VAC, and 10 million mechanical cycles. The power-up delay is set to minimum during setup, and nuisance trip delay is adjustable from 0.2 to 20 seconds. The relay operates from 0°C to 55°C and stores from -10°C to 85°C. Weight is 18 oz.
