ABB TA75DU-25 Thermal Overload Relay

The ABB TA75DU-25 Thermal Overload Relay is a three‑pole protective device for three‑phase motors, rated for up to 600 V with a current setting range of 18 to 25 A (full‑load current). Designed to pair with ABB low‑voltage motor controllers, this TA75DU‑25 module provides thermal protection by monitoring motor current and triggering a trip to prevent winding damage from overheating. The 18–25 A range targets a broad class of mid‑size motors, making it a versatile choice for industrial pumps, fans, conveyors, and other 3‑phase equipment in manufacturing and process environments. As part of ABB’s TA75DU family, it is intended for integration into motor control panels where reliable overload protection and resettable fault handling are essential for safe, continuous operation.
