DCS800-S02-0260-04 DC drive: current class, converter arrangement and service planning
The ABB DCS800-S02-0260-04 is an industrial DC-drive converter in the 260 A frame class. ABB’s DCS800 hardware manual lists the S02-0260-04 type in its current-rating tables. The usable rating depends on converter quadrant, overload duty, line conditions and cooling; confirm the manual’s exact column and the installed motor data before specifying the unit.
Key technical data
| Technical item | Verified value / selection note |
|---|---|
| Type designation | DCS800-S02-0260-04 |
| Converter family | DCS800-S02 industrial DC drive |
| Nominal DC current | 260 A family rating; operating duty and quadrant affect usable current |
| Supply code | -04 version; check voltage and converter wiring in the manual |
| Application | DC motor armature control; field supply and motor details are separate checks |
| Overload reference | Duty-specific short-time current curves apply |
| Retrofit concerns | Verify motor field, feedback, control board, firmware and cabinet cooling |
The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
DC-drive replacement requires more than matching armature current. Check motor armature and field ratings, speed feedback, regenerative or non-regenerative operation, braking, line reactor and control interface. Confirm whether the application needs a single converter, four-quadrant system or separate field supply, and review any legacy PLC/drive communication dependencies.
Configuration and compatibility
Verify the -04 voltage version, converter size, control board, firmware, field supply, feedback device and cabinet ventilation. Confirm the supply network and protection coordination against ABB’s hardware manual. Do not infer the motor’s allowable current from a converter type string without checking the duty class and nameplate.

Installation and commissioning
Use qualified personnel and the prescribed high-voltage isolation and stored-energy procedures. Inspect the converter, buswork, fuses, cooling fan and motor field circuit before energizing. Back up parameters, verify feedback polarity and current limits, and test stop, field-loss and overcurrent protections before returning the drive to production.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation DCS800-S02-0260-04, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
