A Digital Overload Protection Relay is an electronic device designed to protect electric motors and circuits from damage caused by overload conditions. It continuously monitors the current flowing through the motor and trips the circuit if the current exceeds a preset limit for a certain period, preventing overheating and potential motor failure.
These relays use digital technology for precise measurement, easy setting adjustments, and enhanced reliability compared to traditional electromechanical relays. Many models include features like adjustable trip curves, communication interfaces, and diagnostic capabilities. Digital overload protection relays are essential in industrial applications to ensure motor safety, reduce downtime, and extend equipment lifespan.
