Frequently asked questions
Can I use this fuse on a 220 V mains circuit?
Its 250 V AC rating is above 220 V mains, so the voltage rating is sufficient. Mains circuits still require a proper enclosure, insulation and safety practice, and you must follow local electrical safety rules.
What is the difference between a slow-blow and a fast-blow fuse?
A slow-blow (time-delay) fuse tolerates short current surges, such as motor start-up or transformer inrush, without opening. A fast-blow fuse opens quickly on the same surge, so it suits sensitive electronics with no large inrush.
