Westking's HSF21J high-speed fuse
is designed for North American style applications. It is rated for 150 Vac/dc (UL) and can handle currents ranging from 70 to 400 A. This type of fuse is commonly used for the protection of DC common bus, DC drives, power converters/rectifiers, and reduced rated voltage starters. The North American style bolted tag high-speed fuses offer reliable protection and efficient performance in various electrical systems.
Westking's HSF21J high-speed fuse is primarily designed to protect lithium batteries and semiconductor equipment, including power converters/rectifiers, buck starters, and other related devices. Lithium batteries are becoming increasingly popular due to their high energy density and environmental friendliness, but they require proper protection to prevent overvoltage, overcurrent, and short-circuit conditions.
In summary, Westking's HSF21J high-speed fuse is a robust and reliable solution for protecting DC circuits in North American style applications. With its high current rating and fast-acting mechanism, it offers excellent protection for a variety of electrical systems.
