Product Description

The ABB REF615 (part number HBFDACAFNEA1ANN11G) is an advanced feeder protection and control relay, belonging to the ABB Relion® product family. Designed for the protection, control, measurement, and supervision of overhead lines and cable feeders, it ensures safe and reliable power distribution in medium-voltage networks.

Its compact, withdrawable-unit design simplifies installation, testing, and replacement. The REF615 provides extensive protection functions, including overcurrent and earth-fault protection, voltage-based measurements, and fault location features. These capabilities make it a versatile IED (Intelligent Electronic Device) for modern substations.

The relay also supports multiple communication protocols, including full compliance with IEC 61850, enabling seamless interoperability with other devices in substation automation systems. This ensures improved visibility, control, and reliability across the power network.
