Low Voltage NH Fuses 100A - Reliable Protection from China Suppliers & Factory for Power Systems

NH fuses are essential components in power systems, designed to safeguard electrical equipment from abnormal conditions like overloads and short circuits. These high-quality fuses are predominantly utilized in both AC and DC circuits, with a rated voltage not exceeding 690V. As a leading China manufacturer, we provide reliable NH fuses that meet industry standards. Our factory is committed to delivering exceptional products, making us a trusted choice among suppliers. Ensure the protection of your electrical systems with our top-notch NH fuses today!

    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, NH00, NH1, NH2, NH3, NH4.

    2. Electrical Ratings

    Select a rated voltage equal to or greater than the rated voltage, and the current you require. Too high or too low current cannot effectively protect the circuit.

    3. Fuse Base

    Fuse Base or Fuse Disconnector, we supply both of them, 1pole-4poles, choose the correct one you need.

    Where can I buy NH Fuses?

    Our factory has rich experience in producing NH series fuses. The products have passed CE and can be sold to EU countries. High-quality ceramics and high-quality copper provide better quality. SR brand gives you reliable products and better customer service.

    Frequently Asked Questions (FAQ)

    What is an NH fuse?
    NH fuses (also known as NH Knife Blade Fuses or DIN NH Blade Fuses) are general-purpose fuses defined in the German DIN standard 43620, designed primarily for the protection of conductors.
    Are NH fuses reusable?
    No, NH fuses are one-time fuses. Once they have blown, they must be replaced with a new fuse with the same electrical characteristics.
    What physical sizes of NH fuses are available?
    We supply standard NH fuse sizes including NH00, NH1, NH2, NH3, and NH4.
    How do I choose the correct electrical rating for an NH fuse?
    You should select a rated voltage equal to or greater than the system voltage, and the appropriate current rating required for your circuit. Incorrect current ratings cannot effectively protect the circuit.
    Do you supply compatible fuse bases?
    Yes, we supply both Fuse Bases and Fuse Disconnectors ranging from 1-pole to 4-poles to suit your specific installation requirements.
    Are your NH fuses certified for international markets?
    Yes, our products have passed CE certification and can be sold to EU countries. They are manufactured using high-quality ceramics and copper.
