- ABB 1MRK002239-BBR03 is the R03 execution of the 1MRK002239-BB PSM power supply module for 90–250 V DC auxiliary supplies in protection and control IED racks.
- Confirm the complete 1MRK002239-BBR03 marking, 90–250 V DC auxiliary supply range, receiving IED family, rack position, terminal execution and hardware revision before replacement.
- Isolate the station auxiliary supply, record terminal polarity and rack position, use ESD controls and seat the module only in the documented protection IED hardware configuration.
1MRK002239-BBR03 must remain matched to the receiving protection equipment and project record. Verify IED startup, supply supervision, module diagnostics, communications and all enabled protection functions before returning the bay to service.
