£492.45
The IMO MCOR-5-180 is a heavy-duty thermal overload relay engineered to provide advanced motor protection for high-power industrial motor control systems. Designed specifically for use 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 motor operating life in demanding industrial environments.
Part of the robust IMO MCOR overload relay range, the MCOR-5-180 features an adjustable current setting range of 120 to 180A, making it suitable for protecting large three-phase motors and industrial motor starter assemblies. It includes integrated 1NO + 1NC auxiliary contacts together with manual reset functionality for dependable motor control and fault signalling.
Its industrial direct-mount configuration allows seamless installation onto compatible IMO MC141 to MC176 contactors, creating a safe and efficient motor starter solution for conveyors, pumps, compressors, HVAC systems and heavy industrial automation equipment.
Thermal overload relays such as the IMO MCOR-5-180 are designed to protect large industrial motors from overheating caused by overload conditions, stalled rotors or phase imbalance. By disconnecting the motor before thermal damage occurs, overload relays help improve system reliability and minimise costly downtime in industrial environments.
The MCOR range is specifically designed to integrate directly with IMO MC contactors, creating compact and reliable motor starter assemblies suitable for conveyors, compressors, pumps, HVAC systems and heavy industrial automation equipment.
