Industrial TA200DU200 Thermal Overload Relay

ABB TA200DU-200 Thermal Overload Relay delivers 200 A, 690 V-rated thermal protection for three‑phase main circuits in industrial motor control. As the 200 A variant of the TA200DU family, it provides economical electromechanical protection for the main circuit in 3-pole motor starter assemblies and is designed for use with ABB contactors in motor protection schemes. The unit includes an integrated 1NC-1NO auxiliary contact rated up to 3 A at 120 VAC for signaling or interlocking, enabling simple interconnection with control circuits. It is built for 50/60 Hz operation, with an IP00/IP20 enclosure and compact dimensions of 104 mm W x 126 mm D x 151 mm H, suitable for a wide range of panel layouts. The operating temperature range spans -25 to 55 C, making it suitable for many industrial environments. This TA200DU-200 model sits at the upper end of the TA200DU lineup, which covers 90–200 A, and is intended for reliable motor protection in low-voltage distributions up to 690 V.
