Product Introduction
ABB REB500-BU03-V7-C2-A45-P1-F1-BB1-IO0-R0-OC0-BFP1-EFP0-PD0-DR2-L1-T0 is a bay unit used in the REB500 distributed busbar protection system. It handles signal acquisition and interface duties at the bay level, so the exact option string matters when you are matching an existing substation scheme.
This unit belongs in MV, HV, and EHV busbar protection layouts where the bay hardware must align with the installed CT class, communication path, and relay version. The REB500 platform supports 1 A and 5 A inputs and fiber-optic links up to 1,200 m, but the exact configuration still needs to be confirmed against the OEM datasheet before replacement.
