ABB Starter Overload Relays
ABB starter overload relays are engineered for dependable motor protection and long-lasting performance. These relays are designed to safeguard motors from overloads, phase failures, and excessive current, ensuring safe and efficient operation across industrial, commercial, and manufacturing environments.
ABB overload relays function as precision electromechanical protection devices that sense and react to abnormal operating conditions. By monitoring the heat generated inside the motor, these relays automatically disconnect power when the temperature rises beyond safe limits; preventing damage, downtime, and costly repairs. When paired with ABB contactors and motor starters, these relays form a complete and reliable motor protection system. They are easy to install in compact control panels, requiring no special tools and minimal space. Adjustable trip settings allow users to fine-tune the relay’s performance for specific motor types and operating profiles, providing flexibility for a wide range of applications.
ABB overload relays are available in manual or automatic reset versions, giving operators options for continuous or controlled restart capability depending on the environment and safety requirements. Their proven durability, precision, and ease of integration make them a trusted solution for protecting motors across virtually any industrial system.
FAQs
Q: What do ABB overload relays protect against?
ABB overload relays protect motors from excessive current, phase loss, and overheating, ensuring reliable performance and extended motor life.
