Specially designed for safe use in solar systems, Sigma 800V AC NH Fuses are from the group of fuses with melting wires and ensure that the wire inside melts under the effect of heat and breaks at different points against overload currents and short circuits, and quartz sand fills the gaps between the broken parts, completely cutting off electrical conduction and providing the necessary protection.

Increased safety is provided with the steatite body material, which is extremely resistant to short circuits, pressure and high temperatures. Thanks to the double indicator structure, it is easily observed that the NH fuse is disabled, thus providing less downtime and less cost.
