Low Voltage NH HRC Fuse 100A - Reliable Protection from China's Trusted Suppliers and Factory
Description
NH fuses (also known as NH Knife Blade Fuses or DIN NH Blade Fuses) were defined in the German DIN standard 43620 around 1944. They were primarily designed as general purpose fuses for the protection of conductors. NH fuses are one-time fuses, meaning once they have blown, they must be replaced with a new fuse with the same characteristics.
NH Fuse Construction
NH fuses are constructed from a rectangular ceramic casing enclosed by a cover plate that features a metal blade style terminal on each end. The fuse element inside the casing is connected to the cover plate / blade terminals. The majority of NH Fuses have a trip indicator to show if the fuse element has blown. Each cover plate includes a metal extraction lug that enables quick removal of the fuse from a holder when using the recommended NH fuse puller tool.
How to choose NH fuse?
1. Physical Dimensions
Choose the correct size from the available standard options: NH00, NH1, NH2, NH3, NH4.
2. Electrical Ratings
Select a rated voltage equal to or greater than the circuit voltage, and the current you require. Too high or too low current cannot effectively protect the circuit.
3. Accessories & Bases
Choose the correct Fuse Base or Fuse Disconnector. We supply both of them, available in configurations from 1-pole to 4-poles.
