Product Overview

• Part No: MVTU11K1CD0751G
• Brand: ALSTOM

• Category: Low Load Protection RelayMVTU11K1CD0751G belongs to ALSTOM classic MVTU series plug-in static relay. It continuously monitors operating current to detect underload / low-load operating conditions for motors and rotating equipment. When load drops below preset threshold and persists for set delay, the relay activates contact outputs for alarm or equipment interlock, preventing damage caused by long-term light-load operation. Equipped with adjustable setting knobs and transparent protective cover, it is widely used as replacement spare in thermal power plants and distribution substations.
