Why Choose the IMO U12/16E30-MC Thermal Overload Relay?
The IMO U12/16E30-MC is a high-performance thermal overload relay designed to provide dependable motor protection in industrial automation, machinery and motor control systems. As part of the IMO U12/16E overload relay series, it protects three-phase motors against overload conditions and phase failure while integrating directly with compatible IMO contactors.
This overload relay provides adjustable thermal protection with a manual reset function, helping prevent motor damage caused by excessive current draw and prolonged overload operation. Its direct contactor mounting design allows simple installation within motor starter assemblies and industrial control panels.
With an adjustable current setting range of 22–30 A, star-delta motor protection from 38–52 A, and compatibility with IMO MC10–MC22 contactors, the IMO U12/16E30-MC is suitable for protecting medium-sized motors used in conveyors, pumps, compressors and industrial machinery.
