ABB TA25DU-1.8 Thermal Overload Relay 1.3 to 1.8 A

ABB TA25DU-1.8 thermal overload relay provides robust motor protection with an adjustable current setting of 1.3 to 1.8 A, enabling precise coordination with the motor’s full-load current. As part of ABB’s TA25DU family, it is an electromechanical overload relay for the mains circuit intended for use with contactors in low‑voltage motor starter assemblies. For this setting range, ABB documentation lists a trip class of 20, helping ensure predictable protection against overload. Typical applications include protection of small to mid‑size motors in industrial automation, such as conveyors, pumps, and fans, where reliable overload protection must be integral to the control circuit. This variant is specifically the TA25DU-1.8 (1.3–1.8 A) and is supported by ABB and distributor listings from sources such as ABB’s own product pages and major distributors like Farnell and Mouser.
