IMO U12/16E9K1 thermal overload relay with 6–9 A adjustable protection range, manual reset and direct mounting for MB09 contactors.
£39.68
The IMO U12/16E9K1 is a compact and reliable thermal overload relay designed to provide dependable motor protection in industrial automation, machinery and electrical control systems. As part of the IMO U12/16E overload relay series, it protects motors against overload conditions and phase failure while mounting directly onto compatible IMO MB09 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 straightforward installation within motor starter assemblies and industrial control panels.
With an adjustable current setting range of 6–9 A, star-delta motor protection capability of 10.5–15.5 A, and compatibility with IMO MB09 contactors, the IMO U12/16E9K1 is suitable for protecting small and medium-sized industrial motors used in conveyors, pumps, compressors and automation equipment.
Thermal overload relays such as the IMO U12/16E9K1 monitor motor current and disconnect the control circuit when prolonged overload conditions occur. This helps reduce the risk of overheating, winding damage and premature motor failure in industrial environments.
The U12/16E series is designed for machine builders, electrical engineers and control panel manufacturers requiring dependable motor protection integrated with contactor starter assemblies. Its adjustable settings and compact construction provide a practical solution for industrial motor control systems.
