TA2X3.2-65 ABB TThermal overload relay Provide efficient reliable motor protection
ABB TA2X3.2-65 is a high-performance thermal overload relay, specifically designed to protect small and medium-sized three-phase asynchronous motors from overload and phase loss faults. This model supports one normally open (NO) auxiliary contact and features high-precision thermal protection. It is widely used in industrial automation, building automation and infrastructure projects. It can be used in conjunction with contactors to provide a comprehensive motor protection solution, and it features a compact design and high reliability.
Key features
Adopting the principle of bimetallic strip thermal sensing, the tripping characteristic complies with the IEC/EN 60947-4-1 standard (Class 10A), ensuring that the power supply of the motor is cut off in time when overloaded.
It is equipped with a built-in three-phase current imbalance detection mechanism. Once any phase is disconnected, it will trigger a trip to prevent the motor from burning out due to single-phase operation.
