Description

Product Introduction

ABB REF615 HBFHAEAGABC1BBN11G is a feeder protection relay for utility and industrial MV distribution. It protects overhead lines and cable feeders in radial, looped, and meshed networks, with or without distributed generation.

This unit supports directional and non-directional overcurrent and earth-fault, plus voltage, frequency, and power-based functions. It comes with IEC 61850 Ed. 1/2 (GOOSE, IEC 61850-9-2 LE), Modbus, DNP3, and IEC 60870-5-103. The withdrawable plug-in design speeds replacement. Honestly, that cuts swap time in the field.
