NH series fuse SENTRON 3NA COM

Why NH series fuse SENTRON 3NA COM?

The NH series fuse SENTRON 3NA COM provides overload and short-circuit protection for local grids. Enhance substation transparency and safety by detecting current direction and supplying grid optimization data.

Decentralized energy sources complicate grid operations, hindering transparency and rapid fault diagnosis. The HRC (high rupturing capacity) fuse SENTRON 3NA COM provides data to monitor energy flows, detect faults early and optimize your grid. Detect current direction to identify bottlenecks and locate faults quickly.

Achieve transparency with measurement and communication functions. The modular design offers sustainable protection; replace only the fuse, reuse the communication module. Upgrade existing substations with its identical design, wirelessly transmitting data to SICAM EGS for seamless integration.
