ABB TA200DU90 Thermal Overload Relay

The ABB TA200DU90 Thermal Overload Relay is an electromechanical motor-protection device in ABB's TA200DU family, designed to mount with compatible ABB AF contactors to protect the main circuit of a motor-control system from overload and current rise. For the TA200DU90, the protection setting is adjustable in the 80–110 A range, and the unit is catalogued as 1SAZ421201R1001, making it suitable for motor sizes that fall within this segment. The relay weighs about 0.755 kg per unit and is part of the TA200DU family, which spans protection ranges from roughly 66–200 A across variants; compatibility with accessories such as a reset push button (for example KPR-101L) is documented. Typically installed in industrial motor-control panels to protect main circuits, it coordinates with ABB AF contactors (such as AF190 and AF205) to deliver dependable overload protection in applications where ABB control gear is used.
