Features:
- 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. The 1MRK002239-BBR03 must be selected by its complete ABB article number, documented hardware execution, installed position and every mechanical or electrical interface that determines compatibility. Visual similarity alone does not establish interchangeability, so the supplied unit must be compared with the original equipment and approved service record before installation.
Before replacing 1MRK002239-BBR03, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The 1MRK002239-BBR03 ABB PSM power supply module is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB 1MRK002239-BBR03 documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
Use the module only with the documented 90–250 V DC station auxiliary supply and protection IED power architecture.
Match the receiving rack, slot, terminal execution and complete R03 hardware identity before exchanging the supply module.
Confirm stable startup, supply supervision, diagnostics and enabled protection functions after installation.
