NH fuses are one-time fuses, meaning once they have blown, they must be replaced with a new fuse with the same characteristics.
What is NH fuse?
NH fuses (We call it NH Knife Blade Fuses or DIN NH Blade Fuses) were defined in the German DIN standard 43620 … NH fuses are one-time fuses, meaning once they were blown, they must be replaced with a new fuse with the same characteristics.
NH fuse class gG which means general purpose fuse, also called fuse class gL. gG class fuse element will melt within 2–5 seconds at 5 times of the rated current, and within 0.1–0.2 seconds at 10 times of the rated current.
Comparing with the semiconductor fuse, NH fuse is time delay fuse. Which blow slower than high speed fuse, a very fast acting fuse might open in 0.1 second.
Recently due to some plant leadtime is not stable, you can select the fuse cross reference for urgency.
Pls remember to consult Bussmann Power for detail fuse body size, fuse indicator position, fuse microswitch size etc.
