ABB TA25DU6.5 Thermal Overload Relay TA25DU6.5

The ABB TA25DU6.5 thermal overload relay provides motor protection by monitoring the main-circuit current and tripping to interrupt power when an overload is detected. This 4.5–6.5 A variant is part of ABB’s TA25DU family and is available as the TA25DU6.5M version designed for mounting with ABB A‑line contactors, including A/AE/AL series. It is rated for up to 600 V and is UL-listed, making it suitable for integration into standard low‑voltage motor control circuits in industrial panels. An auxiliary 1NC‑1NO contact option is available for the TA25DU6.5M, enabling basic interlocking or starter-signal wiring with the contactor logic. Typical applications include protection of induction motors in star–delta or direct‑on‑line configurations, such as conveyors, pumps, fans, and machine tools, where motor current falls within the 4.5–6.5 A range.
