        More Information

        Overview Manuals Current Selection Mounting Reset and Test Application
        • Protects motor circuits against sustained overload and phase failure
        • Offers selectable manual or automatic reset and front trip indication
        • Uses isolated normally closed and normally open control contacts

        TA25DU-M is ABB's screw-terminal Class 10A thermal-overload family covering multiple current-setting variants.

        The relay uses three bimetal tripping elements and changes the 95–96 and 97–98 auxiliary-contact states when an overload or phase-loss condition causes a trip.

        The exact current suffix, contactor frame, mounting method, reset strategy, conductors, and terminal torque must be established before selection.

        Availability, condition, price, and shipping time for TA25DU-M are confirmed during quotation.

        • Read motor full-load current from the approved nameplate and design data
        • Select the complete TA25DU suffix whose adjustment range covers that current
        • Check short-circuit coordination and protective-device requirements for the selected variant
        • Confirm direct-mount compatibility with the selected ABB contactor frame
        • Use the correct DB25 separate-mounting kit when DIN-rail installation is required
        • Apply the documented conductor preparation and terminal tightening torque
        • Select manual or automatic reset from the machine safety and control strategy
        • Use the front TEST and STOP functions only under the documented procedure
        • Investigate overload and phase-loss causes before returning the motor to service
        • Three-phase motor overload and phase-loss protection
        • Single-phase motor protection using the documented wiring arrangement

        Description
        TA25DU-M is an ABB three-pole thermal overload relay family with screw terminals and Class 10A tripping.

        It protects motors against sustained overload and phase failure and provides isolated normally closed and normally open auxiliary contacts for the control circuit.

        Before selection, choose the complete current-setting suffix, match the contactor or separate-mounting kit, verify conductor size and torque, and confirm the required reset mode.

        TA25DU-M TA25DU M ABB TA25DU-M ABB TA25DU M TA25DU-M Thermal Overload Relay ABB TA25DU-M Thermal Overload Relay
        Technical notes
        TA25DU-M selection requires the complete current suffix, motor full-load current, compatible contactor or DB25 kit, reset strategy, conductor size, and torque; the family name alone is insufficient.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How should the correct current version of ABB TA25DU-M be selected?
        Use the motor nameplate current and coordination study to select the complete TA25DU current-setting suffix; TA25DU-M alone describes a family, not one setting range.
        Can ABB TA25DU-M mount directly on any ABB contactor?
        No. Confirm the contactor frame and approved overload-relay combination; separate mounting requires the correct ABB DB25 kit for the selected current variant.
        Should ABB TA25DU-M be set to manual or automatic reset?
        Select the reset mode from the machine risk assessment and control design. Automatic reset must not create an unexpected restart hazard.
        What should be checked after ABB TA25DU-M trips?
        Investigate motor load, phase condition, supply imbalance, conductor and terminal condition, relay setting, ambient temperature, and mechanical binding before resetting.
        Can ABB TA25DU-M serve as the only protection device in a motor starter?
        No. It provides overload protection, while the starter design must also include the correctly coordinated short-circuit protective device, contactor, isolation, and control-circuit safeguards required by the application.
        How should ABB TA25DU-M be integrated into an existing starter control circuit?
        Follow the approved starter schematic for the trip and indication contacts, then confirm contactor-coil control, interlocks, reset behavior, and protection coordination before returning the motor to service.
        What is the main ordering risk with ABB TA25DU-M?
        Ordering only the family name omits the current suffix; the wrong setting range, contactor frame, or mounting accessory can make the relay unusable.
