Product Introduction
Origin story first — the ABB REF615E is part of ABB’s Relion® 615 family, designed for medium-voltage feeders in industrial substations, utility networks, and switchgear retrofits. The unit integrates protection logic, event recording, breaker control, and IEC 61850 communication in a compact, plug-in module.
Compared to earlier REF54x or SPACOM platforms, this “E” variant improves trip coordination, reduces fault isolation time, and supports PRP/HSR redundancy. In field deployments of AC800M or MicroSCADA systems, engineers select REF615E for fast selective tripping, seamless integration into digital substations, and reliable data exchange over Modbus RTU/TCP or IEC 61850. Trip response is typically <20 ms depending on protection stage configuration.
