Why Choose the IMO U12/16E4-MC Thermal Overload Relay?
The IMO U12/16E4-MC 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 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 enables fast installation within motor starter assemblies and industrial control panels.
With an adjustable current setting range of 2.7–4 A, compatibility with IMO MC10–MC22 contactors, and auxiliary contacts for control signalling, the IMO U12/16E4-MC is suitable for protecting small industrial motors, pumps and machinery applications.
