ABB TA25-DU25 Thermal Overload Relay

The ABB TA25-DU25 Thermal Overload Relay is an electromechanical motor protection device designed for three‑phase motors in industrial environments, providing overload protection and phase‑loss sensing when used with ABB contactors or mounted separately. It features an adjustable current range of 1.0 to 1.4 A, a Class 10A trip, and 1 NO + 1 NC auxiliary contacts; rated insulation voltage Ui 690 V and rated for DC or 50/60 Hz operation. The TA25DU series is compatible with ABB contactors A9 to A40, AX9 to AX32, AL9 to AL40, and TAL9 to TAL40, and is commonly installed in conveyor systems, pumps, compressors, HVAC equipment, and manufacturing machinery to protect motors and minimize downtime. Environmental and compliance specs include IP20 protection, operating temperature from -25°C to +55°C, rated for IEC 60947-4-1, UL, CSA, and CE, and mounting options that allow direct mount to a contactor or separate mounting.
