Frequently Asked Questions

Q: What is the difference between a fast-blow and slow-blow glass tube fuse?

A: A fast-blow (quick-acting) fuse like these 5×20mm glass tube fuses blows almost instantly when the rated current is exceeded, making them ideal for protecting sensitive electronics such as circuit boards and audio equipment. A slow-blow fuse tolerates brief current surges (like motor start-up inrush) before blowing. Always match the fuse type specified in your device's manual for safe and proper protection.

Q: How do I know which amperage fuse to use for my device?

A: Check the label on your device, the user manual, or the existing fuse currently installed. The fuse amperage should match the manufacturer's specification exactly — never install a higher-rated fuse than recommended, as this can create a fire or shock hazard. This 0.2A–20A assortment kit covers the most common ratings so you'll always have the correct replacement on hand.

Q: Are these 5×20mm fuses compatible with standard fuse holders?

A: Yes. The 5×20mm (approximately 0.2″ × 0.79″) dimension is a globally standardized size used in millions of devices and panel-mount fuse holders. They are compatible with the vast majority of PCB and in-line fuse holders designed for this size. For a matching fuse holder, see our 22AWG Glass Tube Fuse Holder.

Q: How are the fuses packaged and organized?

A: All 100 fuses arrive pre-sorted by amperage rating in a durable, labeled plastic component storage box measuring 130 × 64 × 22 mm. Each compartment holds 10 fuses of the same rating, making it easy to grab the right fuse quickly and keep your workspace organized.
