The ABB TA25DU-1.8M is a high-performance thermal overload relay engineered to protect motors operating in the 1.30 to 1.80 A current range. It safeguards motors from overloads, phase failure, and unbalanced conditions by tripping the circuit when abnormal conditions are detected. Designed to be mounted directly on ABB contactors, this relay is ideal for compact motor starter assemblies.
