Description
Product Introduction
ABB REF615 HBFFAEAGNDC1BBA11G is a medium-voltage feeder protection and bay control relay from the Relion 615 platform used in utility substations and industrial MV switchgear. It integrates protection, measurement, breaker control, and communication into a single IED designed for distributed feeder automation systems.
ABB REF615 HBFFAEAGNDC1BBA11G is typically deployed in feeder outgoing bays where directional protection and IEC 61850-based SCADA integration are required. Field commissioning experience shows that system issues are dominated by CT polarity errors, GOOSE dataset mismatch, and firmware alignment problems rather than hardware failures.
Frequently Asked Questions
Q: Is REF615 HBFFAEAGNDC1BBA11G hot-swappable?
A: No. Even with the breaker open, auxiliary DC supply (typically 110–220 V DC) remains energized. Full isolation is required before removal.
Q: Is this relay still supported by ABB?
A: Yes. The Relion 615 series remains an active product line with firmware support, tools (PCM600), and lifecycle services.
Q: What is the most common commissioning failure?
A: Incorrect IEC 61850 GOOSE mapping and CT polarity reversal. These issues often appear as false trips or blocked interlocking.
Q: Will I lose settings during replacement?
A: Yes unless backed up. Always export relay configuration, logic files, and event logs before removal.
