Product Short Description
The ABB REF610C11HCNN01 is a compact, high-performance multifunction protection relay belonging to ABB’s Relion® 600 series. It is purpose-built for protection, control, measurement, and monitoring of medium‑voltage (3 kV–35 kV) feeders in resistance‑earthed and solidly earthed power distribution systems. This plug‑in unit integrates comprehensive overcurrent, earth‑fault, thermal overload, and optional arc‑fault protection with advanced automation and communication capabilities. Designed for utility distribution substations, industrial power systems, and marine/offshore applications, it delivers fast fault detection, reliable isolation, and seamless integration into legacy and modern substation automation architectures. The C11HCNN01 suffix denotes a specific hardware configuration optimized for standard feeder bay applications with robust I/O and communication interfaces.
