NH fuses, also known as blade-type fuses or HRC (High Rupture Capacity) fuses, are essential overcurrent protection devices designed for low-voltage power distribution systems. These fuses are characterized by their robust blade contacts, which allow for secure insertion into fuse bases or switch-disconnectors. Rated for voltages typically up to 690V AC and current ratings ranging from 2A to 1250A, NH fuses offer high breaking capacity, often exceeding 100kA, making them suitable for protecting cables, motors, transformers, and other electrical equipment against short circuits and overloads. They are available in standard sizes such as NH00, NH0, NH1, NH2, NH3, and NH4, each corresponding to specific current ranges and physical dimensions. The fuse elements are typically made of silver or copper, embedded in sand for arc quenching, ensuring reliable and fast interruption of fault currents.

NH fuses are predominantly used in industrial and commercial electrical installations, including main distribution boards, sub-distribution panels, motor control centers, and switchgear assemblies. They are critical in sectors such as manufacturing, energy, infrastructure, and building services, where protection of power circuits and equipment is paramount. Common applications include feeder protection, motor branch circuits, transformer protection, and backup protection for circuit breakers. Their high breaking capacity makes them ideal for installations with high prospective short-circuit currents, such as in large factories, data centers, and utility substations.

The NH fuse category includes several subcategories and key article codes. The main subcategories are NH fuse links (e.g., SI0512.001 for NH00 100A, SI0512.002 for NH0 160A, SI0512.003 for NH1 250A, SI0512.004 for NH2 400A, SI0512.005 for NH3 630A, SI0512.006 for NH4 1250A), NH fuse bases (e.g., SI0512.101 for NH00 base, SI0512.102 for NH0 base), and NH fuse switch-disconnectors (e.g., SI0512.201 for NH00 switch-disconnector). The article code structure typically follows the pattern SI0512.XXX, where XXX indicates the specific size and rating. For example, SI0512.001 represents an NH00 fuse link rated at 100A, while SI0512.101 represents an NH00 fuse base.
