Product Introduction
Substation teams replacing feeder protection during scheduled outages need fast, compatible spares. The ABB RED615C_E HCDCACADAHC2BAN11E functions as a dedicated line differential protection and control IED for overhead lines and cable feeders.
It provides selective unit protection with phase-segregated differential elements plus backup overcurrent and voltage functions. This setup works well in radial, looped, or meshed networks, including those with distributed generation. Typical differential trip times stay low when communication links remain healthy.
