Description
Square body fuses are a very suitable solution for high voltage and high current rated applications that require a compact design and excellent electrical performance. Square body fuses are available in a variety of different end fittings including: DIN 43653, DIN 43620, Flush End, French and American Style. Square body fuses are also available with visual indications and different types of microswitch.
As one type of the square body fuses, Chifeng's American bolt type square body fuses are specially designed for protection of power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs etc. Chifeng provides optimal circuit protection for power semiconductor applications with bolt blade mounting and visual indicators.
