FAQ on ABB TA110DU-110 Thermal Overload Relay
The primary function of the ABB TA110DU-110 Thermal Overload Relay is to provide reliable electromechanical protection for motors and main circuits. It prevents motor damage by detecting overloads and phase failures, thus maximizing the lifespan of connected equipment and minimizing downtime. It operates within a current range of 80 to 110 amps.
Several key features contribute to the reliability of the TA110DU-110 relay. These include:
Trip Class 10A: This ensures fast and effective tripping under overload conditions.
Temperature Compensation: The relay provides consistent protection even with fluctuating ambient temperatures.
Trip-Free Mechanism: This allows for accurate and reliable tripping regardless of the manual reset position, preventing damage from continued overload situations.
Automatic and Manual Reset Options: Allowing the user to select a reset mode that suits the application.
Comprehensive Safety Functions: Including NC trip contact, NO signal contact, STOP and Test functions, and a trip indication.
The TA110DU-110 is designed for direct connection to block contactors, which simplifies the installation process. This direct connection reduces the need for additional wiring and components. Single mounting kits are also available for further simplified installation.
A “trip-free mechanism” in an overload relay means that once the relay trips due to an overload condition, it will remain tripped even if the reset button is held or forced. This ensures the motor does not restart under an overload, which would cause further damage. This functionality allows for a safe and reliable response to overloads.
The relay offers both automatic and manual reset options. Automatic reset will re-engage the motor after a cooling off period. The manual option requires the operator to manually reset the relay after the overload event has passed. Automatic reset may be more useful in fully automated or hard to reach systems while manual reset might be more useful when one needs to investigate the cause of the trip.
The TA110DU-110 has the following key specifications:
