Industrial UKH-22 0.4-0.63 N 0.4-0.63A Thermal Overload Relay

Yagi Kripal UKH-22 0.4-0.63 N 0.4-63A is an industrial thermal overload relay designed to protect three-phase motors in motor control circuits. It provides thermal overload protection for motor starters and contactors, with a current adjustment range of 0.4–0.63 A, a trip class of Class 10A, and one normally open plus one normally closed trip contact. The UKH-22 is compatible with magnetic motor starters and contactors in the C09–C22 range and can mount via direct plug-in or panel mounting in motor control centers, conveyors, HVAC systems, compressors, pumps, and other industrial equipment. Common replacements include Schneider Electric LRD04, Allen-Bradley 193-EA1CB, and Siemens 3RU2116-1AB0, making it suitable for motor protection retrofits and automation repairs in manufacturing environments.
