IMO MCOR-1-6 thermal overload relay with adjustable 4-6A current range, manual or automatic reset and 1NO plus 1NC auxiliary contacts for industrial motor protection applications.
Original price was: £43.57.£28.96Current price is: £28.96.
The IMO MCOR-1-6 is a high-performance thermal overload relay engineered to provide reliable motor protection for industrial control and automation 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 extend motor life and reduce downtime in demanding industrial environments.
Part of the proven IMO MCOR overload relay range, the MCOR-1-6 features an adjustable current setting range of 4 to 6A, with star-delta protection support up to 7 to 10.5A. It includes manual and automatic reset functionality together with integrated 1NO + 1NC auxiliary contacts for flexible control circuit integration.
Its compact direct-mount design allows seamless installation onto compatible IMO contactors from the MC10 to MC22 range, creating a safe and efficient motor starter solution for industrial machinery, pumps, fans and automation equipment.
Thermal overload relays such as the IMO MCOR-1-6 are designed to protect 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 a compact and reliable motor starter assembly suitable for machinery, conveyors, HVAC systems and automation equipment.
