What is an NH1 fuse?
The NH1 fuse is a NH-type fuse that has a particular breaking capacity and rated current. It is frequently utilized in electrical systems that require medium to high power, such as generators, motors, and power distribution systems. The "1" in NH1 indicates that it has a lower breaking capacity compared to NH00 and NH2 fuse sizes, but it has a higher breaking capacity than NH0 fuse size.
The NH1 fuse ceramic body's product characteristics are generally defined by international standards like IEC 60269-1 and DIN VDE 0636. These standards outline the following product features for NH fuse ceramic bodies:
Electrical insulation: The NH1 fuse ceramic body must possess high electrical insulation properties to ensure the electrical system's proper functioning and safety.
Mechanical strength: The NH1 fuse ceramic body must have enough mechanical strength to withstand the forces generated while the fuse is in operation.
High-temperature performance: The NH1 fuse ceramic body must be capable of enduring high temperatures without losing its mechanical or electrical properties.
Resistance to thermal shock: The NH1 fuse ceramic body should be able to resist thermal shock, which occurs when a material rapidly expands or contracts due to a sudden temperature change.
Chemical resistance: The NH1 fuse ceramic body must resist chemical corrosion from the surrounding environment and any materials it may come into contact with.
Breaking capacity: The NH1 fuse ceramic body must be capable of breaking the rated short-circuit current without causing any safety hazards or failing.
