Features:
- ABB product ID DCF1127119R0001 identifies overvoltage protection DCF506-0520-51. ABB technical information expands the code as DCF506-0520-51-0000000 for 250–520 A and 400–500 V equipment.
- Match DCF1127119R0001, the full DCF506 code, 250–520 A class, 400–500 V application, terminals, mounting and the receiving field-exciter diagram.
- Check continuity and insulation, then prove the protected field path and verify that no field overvoltage alarm remains.
DCF506-0520-51-0000000 must be selected from the complete manufacturer identity and the receiving-system evidence. Use it only in the DCF50x field circuit documented for this overvoltage-protection option. Isolate the converter and field circuit, prove discharge and label the field and control conductors before removal.
