Industrial UKH-22 12-18 N 12-18A Overload Relay

The Yagi Kripal UKH-22 12-18 N 12-18A thermal overload relay provides Class 10A thermal overload protection for three‑phase motors within industrial motor control systems. It offers a 12–18 A current adjustment range and can be mounted either as a direct plug‑in unit or on a panel, compatible with C09–C22 contactors used in magnetic motor starters and control panels. The relay features 1 normally open and 1 normally closed trip contact to signal fault conditions and reliably interrupt motor power when overcurrent occurs, making it suitable for conveyors, compressors, pumps, and other automation equipment. Common replacements include Schneider Electric LRD21, Allen-Bradley 193-EA1LN, and Siemens 3RU2116-1MB0, and it complies with GB/T 14048.4 for industrial motor control devices.
