ABB 1MRK0023505-AA – Genuine ABB Spare/Accessory for Relion Protection & Control Systems

• Warranty: 365 days

• Lead time: 1 week if in stock; no more than one month at the latest

• Payment: 50% advance payment; full payment prior to delivery

• Express options: FedEx, UPS, DHL

• Authenticity: Supplied as original ABB part with traceable labeling and ESD-safe packaging

• Compatibility check: We typically verify against your IED type code and serial number to avoid mismatches

• Genuine ABB spare/accessory: Ensures the same mechanical interface and performance characteristics as the original installed component.

• Fit for Relion platforms: Typically used with ABB protection and control IEDs in the 615/620/630/650/670 ranges—ideal for fleet standardization.

• Service-friendly packaging: Supplied in ESD-safe and clearly labeled bags or cartons for simplified storeroom handling.

• Consistent quality: Manufactured to ABB’s QA standards; seems to be the most reliable way to keep multi-vendor panels stable.

• Lifecycle support: Suitable for corrective maintenance, preventive replacements, and retrofit projects to reduce unexpected downtime.

You might notice that maintenance teams prefer OEM-coded parts for mission-critical substations. This part code is typically stocked for:

• Transmission and distribution substations using ABB Relion IEDs

• Industrial power systems (metals, mining, oil & gas, data centers) with ABB feeder/transformer protection

• Retrofit and life-extension programs where compatibility and certification records matter

• Reliability: Original ABB sourcing reduces variability across panels and prevents nuisance faults after maintenance.

• Compatibility: Fit-for-purpose with Relion hardware; avoids engineering re-approval that often comes with substitutes.

• Cost control: Minimizes rework and truck rolls—one thing I appreciate is how these OEM parts shorten outage windows.

• Traceability: Complete part coding for audit, QA, and future spares planning.

• Support: We can align delivery with planned shutdowns; in many cases, advanced shipment notices help your crews stage work.

• Environment: Install within a sealed switchgear/control cabinet that meets the IED’s specified humidity and temperature ranges; keep ventilation unobstructed.

• Wiring: Follow the specific Relion manual for terminal labeling and torque values; isolate control power and trip circuits before work.

• ESD safety: Use grounded wrist straps and antistatic matting; do not remove protective packaging until at the panel.

• Verification: After installation, perform self-tests/diagnostics on the IED and check event logs for errors or warnings.

• Routine care: Periodically inspect connectors and mounting points; keep the cabinet free from dust; schedule firmware checks on the host IED when applicable.

• Typically conforms to ABB’s CE marking where applicable for the host equipment

• RoHS-compliant components and packaging practices in most cases

• Manufactured under ISO 9001 quality management systems

• One-year warranty coverage (365 days) from shipment

A utility customer recently mentioned the swap was “plug-and-play” once we matched the IED type code. That seems to be the norm with ABB-coded parts—minimal recalibration and no surprises during commissioning. If you share your IED type (e.g., REL615, REF630) and serial, we’ll validate 1MRK0023505-AA fitment before you place the order.
