IMO MT5-8 thermal overload relay with an adjustable 8-11 A current range, designed to protect three-phase AC motors against overload and phase-failure conditions.
£0.04
The IMO MT5-8 is a reliable thermal overload relay designed to protect three-phase electric motors against overload conditions and phase failure. Engineered for industrial motor control systems, it helps prevent costly motor damage by disconnecting the control circuit before excessive temperatures can affect motor windings.
With an adjustable current range of 8–11 A, the MT5-8 provides accurate overload protection for a wide range of industrial motors. Its adjustable settings allow engineers to match the relay to the motor's full-load current, ensuring dependable protection and improved equipment reliability.
Designed for direct mounting to compatible IMO contactors, the MT5-8 offers compact installation, straightforward commissioning and selectable manual or automatic reset functionality, making it ideal for control panels, machinery and OEM motor starter assemblies.
The IMO MT5-8 continuously monitors motor current and disconnects the control circuit when prolonged overload conditions occur. This thermal protection helps prevent overheating, extends motor service life and reduces costly downtime while allowing normal motor starting currents without nuisance tripping.
Its adjustable overload range enables accurate matching to the motor's rated current, making it ideal for industrial motor starters, production machinery and automation systems.
