ABB REF615E_E HBFHAEAGNBA1ANN11E Feeder Protection and Control Relay

Description

The ABB REF615E_E HBFHAEAGNBA1ANN11E Feeder Protection and Control Relay is a dedicated device designed for protection, control, measurement, and monitoring of public and industrial power distribution systems. It serves as primary protection for overhead lines and feeders in distribution networks, and can also act as backup protection in systems requiring redundant protection or separated protection and control functions. Compatible with neutral ungrounded, resistance-grounded, and impedance-grounded grids, it supports use in radial and ring mesh distribution networks, including systems with multiple feeders and distributed generation.

Key features include multi-functional integration, with built-in protection for overcurrent, overvoltage, ground fault, loss of voltage, and undervoltage, plus auxiliary functions like remote control and fault recording. It offers high sensitivity and fast response to detect and address faults promptly, ensuring grid safety and stability. Built with industrial-grade components, it delivers high long-term reliability, and supports flexible software configuration to adapt to diverse application scenarios.

With robust communication capabilities, it supports the IEC 61850 substation standard (including IEC 61850-9-2 LE), Parallel Redundancy Protocol (PRP), and High-availability Seamless Redundancy (HSR), as well as DNP3, IEC 60870-5-103, and Modbus protocols. It can also support Profibus DPV1 via the SPA-ZC 302 protocol adapter. The device has a net weight of 4 kg and offers 12 standard configurations for common feeder protection and monitoring applications.
