NH Fuse

NH-series blade-contact fuses are widely used for circuit protection in applications such as low-voltage switchgear, busbar systems, variable frequency drive (VFD) protection, PV combiner boxes, energy storage units, construction machinery, power distribution systems for buildings and ports, and marine infrastructure.

Designed as an internationally standardized protective device for low-voltage AC power distribution circuits, the NH series features low-voltage operation, high breaking capacity, and current-limiting characteristics.

In the event of a circuit fault, the fuse element melts rapidly to interrupt the fault current and extinguish the arc, thereby preventing equipment damage and fire hazards; this effectively protects power grids, transformers, motors, and various electrical devices against overloads and short-circuit faults.

NH-series fuses feature a high-strength ceramic body filled with high-purity quartz sand, while the blade-contact design ensures excellent electrical conductivity and helps lower operating temperatures. To facilitate quick fault identification during operation and maintenance, some models are equipped with an integrated fuse indicator.

This series holds CE certification and complies with international safety standards, making it suitable for export to markets in Europe, the Middle East, Africa, and Southeast Asia.
