Kripal UKH-150 IGBT Module

The Kripal UKH-150 is a 3-pole thermal overload relay engineered for reliable overload protection of three‑phase motors in industrial control systems, with an adjustable 100–150 A trip range to fit larger motors. It mounts directly to Kripal contactors or panel assemblies and delivers thermal overload protection, phase loss protection, and a Class 10A trip, with 1 normally open and 1 normally closed auxiliary contact for signaling or interlocking. Reset can be manual or automatic (selectable), providing flexible operation in motor starters and retrofit projects, while compliance to GB/T 14048.4 helps ensure compatibility with standard industrial motor control equipment. Key specifications include: 3P configuration, current adjustment 100–150 A, trip class 10A, auxiliary contacts 1 NO + 1 NC, and Kripal compatibility, with mounting options for direct contactor mounting or panel mounting. Common applications span motor control centers, pumps, compressors, conveyors, HVAC equipment, and manufacturing machinery needing dependable three‑phase overload protection and phase failure detection.
