IMO MT5-7 thermal overload relay with an adjustable 5.5-7 A current range for protecting three-phase AC motors against overload and phase failure.
£0.04
The IMO MT5-7 is a high-quality thermal overload relay engineered to protect three-phase electric motors from overload conditions and phase failure. Designed for industrial motor control applications, it helps extend motor life by disconnecting the control circuit before excessive heat can damage motor windings.
Featuring an adjustable current setting of 5.5–7 A, the MT5-7 enables accurate motor protection by allowing the relay to be matched to the motor's full-load current. It is ideal for use in machinery, process equipment and industrial automation systems.
Designed to mount directly to compatible IMO contactors, the MT5-7 provides reliable motor protection in a compact format, making it suitable for electrical control panels, OEM equipment and motor starter assemblies.
The IMO MT5-7 continuously monitors motor current and trips when prolonged overload conditions occur, helping prevent overheating and costly motor damage. Its thermal operating principle accurately reflects motor heating characteristics for dependable protection.
Suitable for industrial control systems and machinery, the relay provides dependable performance while allowing easy adjustment during installation and commissioning.
