The ABB TA25DU-24-32 is a thermal overload relay, listed under Contactors and Starters — specifically Thermal Overload Heaters for Starters. It's the part that sits between the contactor and the motor, providing overcurrent protection by sensing motor heating and tripping the contactor coil when the current exceeds the relay's setting range for too long.
Because the TA25DU-24-32 is a current-production part, sourcing it for a BOM line is straightforward — no last-time-buy window to watch, no substitute validation needed.
