ABB REF615 Feeder Protection HBFFAEAGNBA1BNA1XE

·        Directional and non-directional overcurrent and earth-fault protection, voltage, frequency and power based protection and measurement functionality.

·        Extensive earth-fault protection portfolio with unique multi-frequency admittance-based protection for higher sensitivity and selectivity.

·         REF615 has been designed to be the main overcurrent and earth-fault protection for overhead lines and cable feeders, in either isolated neutral, resistance-earthed, compensated or effectively-earthed distribution networks, depending on the standard configuration.

·         Extensive range of protection and control functionality, either with sensors or conventional instrument transformers

·         Ready-made standard configurations for fast and easy setup with tailoring capabilities

·         Withdrawable plug-in unit design for swift installation and testing

·         Large graphical display for showing customizable SLDs, accessible either locally or through an easy-to-use web-browser-based HMI
