Product Introduction
Compare this to standard CT/VT configurations and the ABB REF615G HBFNAEAGANB1ANA11G stands out for combi sensor applications. It integrates current and voltage measurement in one sensor set, cutting wiring and panel space in modern medium voltage switchgear.
This unit targets distribution feeders in utility and industrial sites needing compact, high-sensitivity protection. The order code points to advanced earth-fault handling and IEC 61850 readiness. It supports radial, looped, or meshed networks with or without distributed generation. Field experience shows these combi-sensor variants reduce installation time versus traditional wired setups.
Select it when your project already uses combi sensors or you want future-proof measurement. Typical fault clearing stays under 40 ms on instantaneous elements. Always cross-check the full order code against your bay design before deployment.
