What are the exact technical specifications and physical size of these fuses?

These 250V fast-blow glass cartridge fuses measure 5x20mm (0.2 x 0.78 inches). Available in ratings from 0.1 to 20, please check your original fuse specs and holder size carefully before ordering.

What is the difference between a fast-blow and a slow-blow fuse?

Fast-blow fuses open instantly to protect sensitive electronics as soon as current exceeds the rated limit. Slow-blow fuses tolerate brief start-up surges. Always match your device’s original specifications.

What devices are these fast-acting glass fuses typically used for?

They are commonly used in multimeters, small household appliances, battery chargers, audio equipment, and sensitive electronic devices requiring low-current, fast-acting circuit protection.

How can I tell if one of these glass fuses is blown?

Thanks to the clear glass body, you can visually inspect the internal filament. If the metal wire is broken or visibly burnt, the fuse is blown. You can also verify continuity using a standard multimeter.

Can I use a 250V rated fuse in a lower voltage application, like 12V or 120V?

Yes! The 250V rating indicates the maximum voltage the fuse can safely handle. It can safely be used in lower-voltage applications (such as 12V or 120V) as long as the current rating and physical dimensions match.
