Cartridge Fuse vs Blade Fuse
Cartridge Fuse vs Blade Fuse
Cartridge and blade describe mounting styles, not universal electrical capabilities. A cylindrical cartridge fits clips or a cap holder; an automotive blade fuse fits a matching slotted socket.
Cartridge products range from small electronics fuses to industrial and PV fuses with very different ratings. Blade-style products also come in several forms and ranges. A low-voltage automotive ATO is unsuitable for a mains holder, but it does not follow that all blade fuses are limited to 32 V or that all cartridges have high interrupt capacity.
Begin with the equipment’s holder and original part number. For a new design, determine the voltage, conductor protection requirement and available fault current before selecting the fuse series and holder together. Never adapt one format to another using loose contacts or a makeshift connection.
