Product Introduction

Distribution networks with mixed loads require protection that covers both current and voltage anomalies. The ABB REF615_HBFDACADABC1ANN11G delivers this in one compact IED for overhead lines and cable feeders.

This unit handles non-directional overcurrent, earth-fault, undervoltage/overvoltage, and frequency protection in radial, looped, or meshed systems. It supports utility substations and industrial sites where fast isolation and station bus integration matter. The drawout case simplifies maintenance swaps while maintaining IEC 61850 communication for GOOSE messaging.

Select this model when voltage supervision complements current-based elements. It typically clears instantaneous faults under 40 ms. Verify the full order code against your bay requirements and existing firmware before installation.
