Siemens' NH fuse system is an essential component of the SENTRON protection devices for electrical installations, providing effective protection for people, devices, and systems through safe disconnection in overload and short-circuit situations. Compared to circuit breakers, it can handle higher short-circuit currents while offering better current limitation.

The NH fuse system is characterized by:
1. Combination indicators signal the disconnection of the fuse through a clear color change from red to white.
2. Increased safety during replacement due to insulated grip sleeves.
3. High selectivity at low costs.
4. Long-term and safe operation due to silver-plated contact blades.
5. Fuse inserts available from 2 A to 1250 A and in sizes 000, 00, 0, 1, 2, 3, 4, and 4a.
