The ABB Thermal Overload Relay is a dependable device designed to protect electric motors from damage caused by overloads, prolonged overcurrent, or phase failure. By monitoring the electrical current, it automatically disconnects the motor if unsafe operating conditions are detected. This not only prevents overheating but also extends motor lifespan and reduces costly downtime.
Features and Benefits
Built with ABB’s precision engineering, the thermal overload relay offers accurate performance, even in challenging environments. Its bimetallic strip mechanism ensures a precise response to excessive current and temperature changes. The design also includes temperature compensation, maintaining reliability in varying ambient conditions.
Other advantages include manual and automatic reset options, an adjustable current range to suit different motor sizes, and a compact form factor for easy panel integration. When paired with ABB contactors, it provides a complete and highly reliable motor protection solution.
