ABB TA25 DU 4.0 1SA Z21 1201 R1033 9198 Thermal Overload Relay

ABB TA25 DU 4.0 Thermal Overload Relay (order code 1SAZ 21 1201 R1033) provides electromechanical motor protection for ABB’s TA25 family when used with ABB low-voltage contactors in motor starter configurations. The 4.0 A setting is one of the predefined overload ranges available for the TA25 DU line, with the 1SAZ 21 1201 R1033 configuration specifically corresponding to a 4.0 A setpoint. The unit weighs 0.150 kg per piece and is designed for integration with ABB protection schemes in standard electrical panels and starter assemblies. Typical applications include protecting motors in low-voltage main circuits within ABB A-line starter configurations, where the overload relay trips to prevent damage when the current exceeds the selected setting.
