ABB TA25DU-0,63 Overload Relay TA25 Series 0.4-0.63A

ABB TA25DU-0.63M is a three-pole thermal overload relay in the TA25 family, designed to protect motors controlled by ABB TA contactors. It offers an adjustable current setting from 0.40 A to 0.63 A and supports up to 690 V AC, making it suitable for standard three-phase motor circuits in industrial control panels. The device uses a thermal-bimetal trip element to sense overload and will trip to interrupt the main circuit when the set current is exceeded, helping prevent motor damage from overload or phase issues. It includes one normally open and one normally closed auxiliary contact (1NO/1NC) for signaling and interlocking in the control circuit, and it is compatible with ABB TA-series contactors such as A9, A12, A16, A26, A30, and A40, enabling straightforward integration into existing equipment. This TA25DU-0.63M variant provides a compact, economical protection option for fans, pumps, conveyors, and other machinery that rely on reliable motor protection within ABB’s low-voltage control systems.
