1SAZ431201R1004 ABB - TF140DU-142

The 1SAZ431201R1004, also known as the TF140DU-142, is a thermal overload relay manufactured by ABB. It is designed to provide reliable and effective protection for electric motors against overload and phase failure conditions. This particular model has a current range of 110 to 142 Amperes, making it suitable for motors with corresponding full-load current requirements. The TF140DU-142 offers Class 10 tripping characteristics, which defines the time it takes for the relay to trip under overload conditions. This thermal overload relay is an essential component in motor control circuits, preventing damage to motors and ensuring operational safety. It operates by monitoring the current flowing to the motor and tripping when the current exceeds the set value for a specific duration. The relay is equipped with features such as adjustable current settings and test functions for easy setup and maintenance. Its robust design and reliable performance make it a preferred choice for motor protection applications across various industries. The TF140DU-142 is a direct replacement for TF140DU142.
