WEBER NH0 KTF 100 A IW 1505100 100A 500V

Weber NH0 KTF 100A 500V AC Fuse Description This is a Weber NH-Sicherungseinsatz (NH fuse-link) of size NH0, designed for reliable circuit protection in industrial applications. With a rated current of 100A and a voltage of 500V AC, it provides robust defense against both overloads and short-circuits. The gL/gG characteristic makes it a versatile, full-range fuse suitable for general line and equipment protection. Specifications Manufacturer: Weber Type: NH 0 KTF 100 A Part Number: IW 1505100 Rated Current: 100 A Rated Voltage: 500V AC Fuse Size: NH0 Characteristic: gL/gG (General Line Protection) Breaking Capacity: 120 kA Standards: VDE 0636, IEC 269 Application This fuse is commonly used in industrial distribution boards, switchgear, and control panels to protect cables, power lines, and other electrical equipment from the damaging effects of overcurrents. CO2 Impact Opting for a refurbished or new-old-stock component like this Weber fuse prevents the emission of approximately 3.6 kg of CO2 compared to manufacturing a new one. This saving is equivalent to the emissions from a 18 km car journey. Availability This item is in stock and ready for immediate dispatch.

FAQ What is the difference between gL and gG characteristics?Historically, gL stood for cable and line protection, while gG was for general purpose applications. According to the current IEC standard, the gG class has replaced the gL class, and they are now considered equivalent for most applications. They both provide full-range protection against overload and short-circuit currents. Can this 500V AC fuse be used in a DC circuit?While some AC fuses can be used in DC circuits, their breaking capacity and voltage rating are significantly de-rated. It is critical to consult the manufacturer’s datasheet for specific DC application guidelines. Using it outside of its specified AC rating without verification is not recommended. What are the signs that an NH fuse like this needs replacement?An NH fuse should be replaced after it has interrupted a fault (blown). Most NH fuses have a visible trip indicator on the top metal plate that pops up or changes color (e.g., to red) when the fuse has operated. There is no need for preventative replacement unless the fuse body shows signs of physical damage like cracks or charring. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
