ABB TF140DU-90 (order code 1SAZ431201R1001) is a genuine ABB thermal overload relay: Thermal Overload Relay 66-90 A, Class 10A, 1NO+1NC.
Thermal overload relays are standard parts of every direct-on-line and star-delta starter; a relay that trips repeatedly or no longer resets is replaced with the same type and current range.

Compatibility and replacement
Order with the full type TF140DU-90 or the order code 1SAZ431201R1001; in ABB type designations the last digits select the current range or the coil voltage, so a part with a different suffix is not always a drop-in replacement.
If the old label is worn, send us a photo and we will confirm the matching ABB type before quoting.
What to check first
- Reset mode (manual/automatic)
- Setting range versus the motor full-load current
- Trip class
