The IMO MCOR-1-1.2 is a compact and dependable thermal overload relay engineered to provide reliable motor protection for industrial automation and motor starter systems. Designed specifically for use with the IMO MC contactor range, this overload relay protects motors against overload conditions, excessive current draw and phase failure, helping maximise equipment reliability while reducing downtime in demanding industrial environments.
Part of the trusted IMO MCOR thermal overload relay series, the MCOR-1-1.2 features an adjustable overload setting range of 0.8 to 1.2A, making it ideal for low-current motor protection and precision industrial control applications. Integrated manual and automatic reset functionality together with 1NO + 1NC auxiliary contacts provide flexible fault signalling and dependable motor protection performance.
Its compact direct-mount design allows seamless installation onto compatible IMO MC10 to MC22 contactors, creating a safe and efficient motor starter solution for conveyors, pumps, laboratory equipment, HVAC systems and industrial automation machinery.
Thermal overload relays such as the IMO MCOR-1-1.2 are designed to protect electric motors from overheating caused by overload conditions, stalled rotors or phase imbalance. By disconnecting the motor before thermal damage occurs, overload relays improve system reliability and reduce maintenance costs in industrial environments.
The MCOR range integrates directly with IMO MC contactors, creating compact and dependable motor starter assemblies suitable for industrial automation equipment, control panels and precision low-current motor applications.
