Industrial UKH-22 9-13 N 9-13A Thermal Overload Relay

The Yagi Kripal UKH-22 9-13 N 9-13A Thermal Overload Relay provides thermal overload protection for three‑phase motors in industrial automation and electrical control panels. Designed for use with magnetic motor starters and contactors, it pairs with C09‑C22 contactors to safeguard applications such as motor control centers, conveyors, HVAC systems, compressors, and pumps. The unit offers a adjustable current range of 9–13 A, a Class 10A trip class, and 1 normally open plus 1 normally closed trip contacts, enabling reliable start/stop control and safety interlock in panel installations. Mounting options include direct plug‑in or panel mounting, giving flexible installation in compact control panels or larger motor control assemblies. Compliance to GB/T 14048.4 marks its alignment with recognized industrial standards. In practice, technicians use the UKH‑22 9‑13 N for motor protection replacements, retrofits, and automation repairs, and it is considered a common alternative to other device families such as the Schneider Electric LRD16, Allen‑Bradley 193‑EA1LB, and Siemens 3RU2116‑1LB0. This thermal overload relay is specifically designed for three‑phase motor control systems and is suitable for automation and electrical control panels across manufacturing and processing facilities.
