Genuine ABB 1MRK000173-CCr00 EFORE - Industrial Automation Part

ABB 1MRK000173-CCr00 EFORE Communication Module | Relay Protection Spare Part

Description

ABB 1MRK000173-CCr00 EFORE Communication Module | Replacement, Equivalent & Selection Guide

When a communication module fails in a substation relay protection system, the consequences extend far beyond a single device. Loss of inter-relay communication can blind protection engineers to fault conditions, delay trip commands, and expose critical grid infrastructure to cascading failures. The ABB 1MRK000173-CCr00 EFORE module is a purpose-built communication and frame-processing board designed to maintain the integrity of ABB’s relay protection architecture — its absence is not an option in live grid environments.

Within ABB’s relay protection ecosystem, the 1MRK000173-CCr00 EFORE occupies a critical role as a communication interface and end-of-frame processing unit. It is widely deployed across ABB’s REC, REL, and RED series protection relays in transmission and distribution substations globally, making it one of the most sought-after spare parts in the power automation aftermarket.

Note: Detailed electrical parameters (voltage, current ratings, communication protocol specs) should be confirmed against the ABB relay system documentation for your specific relay model. Konmask does not fabricate specifications.

Compatible Replacement & Equivalent Models

The 1MRK000173-CCr00 EFORE may be cross-referenced or considered alongside the following ABB modules, subject to system compatibility verification:

ABB 1MRK000173-CCr01 (revised revision of same series)
ABB EFORE board variants used in REC 316*4 / REC 523 / REL 316 platforms
ABB 1MRK000173 series communication sub-boards
Third-party compatible communication interface boards (consult Konmask engineering team for validation)

Important: Revision codes (e.g., CCr00 vs CCr01) may affect firmware compatibility. Always verify the revision level against your relay’s hardware matrix before substitution.

Why Choose the Original Model

Guaranteed Compatibility: OEM part number ensures direct fit into ABB relay racks without hardware modification.
Firmware Alignment: Original revision codes are matched to specific relay firmware versions, eliminating communication handshake failures.
Regulatory Compliance: Substations operating under IEC 61850 or NERC CIP standards require traceable, OEM-certified components.
Reduced Commissioning Risk: No re-parameterization or re-testing required when replacing like-for-like.
Long-Term Support: ABB spare parts carry manufacturer traceability, essential for asset lifecycle documentation.

Typical Applications

Transmission substation protection relay systems (110 kV – 500 kV)
Distribution automation and feeder protection panels
Industrial power systems: steel mills, petrochemical plants, mining operations
Railway traction substation protection
Offshore platform and marine power protection systems
Renewable energy (wind/solar) grid-connection protection relay panels

System Compatibility

The 1MRK000173-CCr00 EFORE is designed for integration within ABB’s modular relay protection platforms. Typical compatible host systems include:

ABB REC 316*4 Protection and Control Relay
ABB REC 523 Bay Control Unit
ABB REL 316 Distance Protection Relay
ABB RED 500 series differential protection relays
ABB SPACOM / PYRAMID relay systems (legacy)

Compatibility must be confirmed against the specific relay’s hardware configuration document (HCD) and software version. Contact Konmask’s technical team for cross-reference support.

Selection Guide

Use the following checklist when selecting a replacement EFORE module:

✅ Confirm the exact part number from the relay’s nameplate or hardware configuration document.
✅ Verify the revision code (CCr00, CCr01, etc.) matches the relay’s firmware version matrix.
✅ Check whether the relay requires a new OEM module or if a tested-refurbished unit is acceptable per your maintenance policy.
✅ Confirm slot position and backplane connector type in the relay chassis.
✅ For IEC 61850 environments, verify GOOSE/MMS communication protocol support of the replacement module.

Replacement & Compatibility FAQ

Q: Can I replace 1MRK000173-CCr00 with a CCr01 revision?: A: Possibly, but revision changes may affect firmware compatibility. Always consult ABB’s hardware compatibility matrix or contact Konmask’s technical team before substitution.
Q: Is a refurbished EFORE module safe for substation use?: A: Refurbished units that have passed functional testing are widely used in maintenance scenarios. For critical protection applications, we recommend new OEM units with full traceability documentation.
Q: What is the lead time for this module?: A: In-stock units ship within 1–3 business days. For sourced units, typical lead time is 7–21 business days depending on origin. Contact us for current stock status.
Q: Do you provide a certificate of conformance (CoC)?: A: Yes. CoC and inspection reports are available upon request for all new OEM units.
Q: Can Konmask help identify the correct replacement if I only have the relay model number?: A: Absolutely. Provide your relay model, serial number, and firmware version to support@konmask.com and our engineers will identify the correct EFORE module revision for your system.
