    Product Detail

    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 our standard options: NH00, NH1, NH2, NH3, and NH4.
    2. Electrical Ratings
    Select a rated voltage equal to or greater than your system voltage, and the current you require. Too high or too low current cannot effectively protect the circuit.
    3. Fuse Base or Disconnector
    We supply both options, ranging from 1 pole to 4 poles. Choose the correct configuration you need for your setup.

    Frequently Asked Questions

    What is the origin and purpose of NH fuses?
    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 electrical conductors.
    Can NH fuses be reused after they blow?
    No, NH fuses are one-time fuses. Once the fuse element has blown, the entire fuse must be replaced with a new one that has the exact same characteristics and ratings.
    How can I tell if an NH fuse has blown?
    The majority of NH fuses are designed with a trip indicator on the casing, which visually signals whether the internal fuse element has blown and needs replacement.
    What physical sizes of NH fuses do you offer?
    We offer standard physical dimensions including NH00, NH1, NH2, NH3, and NH4 sizes to match your specific hardware requirements.
    What mounting options do you supply for NH fuses?
    We supply both NH Fuse Bases and NH Fuse Disconnectors, available in configurations ranging from 1 pole to 4 poles.
    Are your NH fuses certified for international markets?
    Yes, our NH series fuses have passed CE certification and can be sold to EU countries. They are manufactured using high-quality ceramics and high-quality copper for reliable performance.
