Siemens NH-Blade Fuse Base 400 A Monophase Length 2 49mm The power loss caused by 3NH3330 fuse-links is very low and the rated circuit opening power is quite high. Siemens NH fuses have the feature of operating with maximum safety, as well as being economical. NH fuse-links are very durable. These plugs perform their duties in a healthy way at different temperatures. The plugs are made in 5 different sizes, starting from 00 to 3. The reason why NH fuses are made in 5 different sizes is that they work with very high current values ​​and are produced to withstand these current values. The name NH comes from the German abbreviation 'Low Voltage High Power' fuse. Each has amperage ranging from 25A to 630A.
