Product Advantage
Three-level closed-loop quality inspection management
All finished NH1 dual indicator ceramic fuse links go through raw material incoming inspection, semi-finished intermediate inspection and finished offline comprehensive performance test. All defective semi-finished and finished products will be marked, isolated and scrapped uniformly, to ensure stable and reliable protection performance of each fuse link delivered to global customers.
Crafted to comply with global IEC and DIN standards, this Ceramic HRC Fuse Link delivers powerful arc suppression and full-range gG overcurrent protection, perfectly matching the load demand of medium-large inverters and centralized energy storage equipment. As a certified NH1 Fuse, it holds complete official certification paperwork, and this NH1 Fuse Link with CE eliminates customs clearance and tender review barriers for cross-border industrial projects. Reinforced with high-temperature sintered insulation, this Ceramic HRC Fuse Link resists thermal deformation under sustained heavy loads, while the precise melt design of the NH1 Fuse Link with CE triggers instantaneous short-circuit isolation to cut equipment downtime and prevent costly production damage.

FAQ
Q1: What current specifications are available for NH1 Fuse Link, can it cover medium-high power PV inverter projects?
A1: The current range of NH1 Fuse Link covers 40A to 250A, including mainstream specs such as 100A, 160A, 200A and 250A. It fully matches medium and large solar inverters, medium-power motors and main branch distribution circuits of energy storage cabinets, widely used in centralized PV stations.
Q2: Does NH1 Fuse Link work normally in both AC 690V industrial circuits and DC 440V energy storage loops?
A2: Yes, its dual rated voltage design supports AC500/690V and DC440V simultaneously. The gG characteristic can effectively restrain startup surge of energy storage equipment and avoid nuisance blowing, offering stable overcurrent protection for hybrid AC-DC power systems.
Q3: Can NH1 Fuse Link be replaced directly with old European imported NH1 fuse without cabinet modification?
A3: Absolutely. Our NH1 fuse strictly follows unified DIN standard dimensions, the blade spacing, overall outline and installation size are fully consistent with imported counterparts. No busbar, cabinet hole or wiring adjustment is needed for one-to-one replacement.
