The IMO MCOR-1-0.27 is a precision-engineered thermal overload relay designed to provide dependable motor protection for industrial automation and motor starter applications. Developed for seamless integration with the IMO MC contactor series, this overload relay protects motors against overload conditions, phase failure and excessive current draw, helping reduce downtime and extend equipment lifespan in demanding industrial environments.
Part of the trusted IMO MCOR thermal overload relay range, the MCOR-1-0.27 features an adjustable current setting range of 0.18 to 0.27A, making it ideal for low-current motor applications and precision industrial control systems. The relay includes integrated 1NO + 1NC auxiliary contacts together with selectable manual and automatic reset functionality for flexible control integration and reliable fault recovery.
Its compact direct-mount design allows seamless installation onto compatible IMO MC10 to MC22 contactors, creating a reliable and efficient motor starter solution for conveyors, laboratory systems, pumps, fans and industrial automation equipment.
Thermal overload relays such as the IMO MCOR-1-0.27 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.
