ABB SPAJ 135 C-AA Earth-Fault Relay – Overcurrent & Earth-Fault Protection

Technical Dossier

Product Details And Specifications

The ABB SPAJ 135 C-AA is a combined overcurrent and earth-fault protection relay widely deployed in medium-voltage switchgear across power utilities, petrochemical plants, steel mills, and heavy industrial facilities. As ABB has progressively transitioned its protection relay portfolio toward the REF/RET series, the SPAJ 135 C-AA has entered a phase of constrained availability — making proactive procurement and RFQ-reviewed sourcing status sourcing a critical risk management decision for asset-intensive operations.

Procurement Specifications

Avoiding Counterfeit Risk: The SPAJ series is a known target for counterfeit reproduction in secondary markets. DriveKNMS sources exclusively from traceable channels — decommissioned OEM projects, certified distributors, and tested surplus — and provides full documentation upon request. Every unit undergoes functional verification before dispatch review.

Price Advantage: By sourcing through DriveKNMS rather than direct OEM channels (where available), customers typically achieve 15–35% cost savings on legacy relay models, without compromising on quality or compliance documentation.

• RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.
• Export Documentation: Full commercial invoice, packing list, certificate of origin, and customs HS code declaration provided for all international shipments. Compliant with EU, US, and ASEAN import requirements.
• Multi-Currency Payment: USD, EUR, CNY, HKD accepted. T/T bank transfer, PayPal, and trade finance arrangements available for qualified buyers.
• Global Logistics: DHL Express, FedEx International Priority, and UPS available. Typical transit: 3–5 business days to Europe/Americas; 2–4 days to Southeast Asia. Air freight and sea freight consolidation available for bulk orders.
• Packaging: Anti-static packaging with foam cushioning. Original OEM packaging preserved where available.

Sourcing Network: DriveKNMS maintains an active sourcing network across 40+ countries, with direct relationships with decommissioning contractors, OEM surplus dealers, and certified repair centers. When a part is not in our warehouse, we locate it — typically within 24–72 hours for common industrial relay models.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Repeat Buyer Program: Customers with recurring MRO needs can establish a standing RFQ agreement with DriveKNMS, enabling priority allocation, pre-negotiated pricing, and dedicated account management.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Q: How do I know the unit is genuine?
A: All units are sourced from traceable channels and undergo pre-shipment functional verification. We provide full sourcing documentation and, where available, original OEM packaging and serial number records.
