UL cUL 2A 250V Quick Fast Blow 3x10mm Axial Leaded F Glass Tube Fuse 2AL250V Cartridge Fuse Link 500pcs Per Bag

Description

A fast-acting 3.6 x 10mm axial-leaded fuse constructed with ceramic tube and one-piece nickel-plated endcaps featuring tinned copper axial leads. Small 3.6 x 10mm size offers more design flexibility by doing away with conventional over-capping while providing higher I2t values.

How do glass tube fuses work?

A glass fuse works by breaking the circuit when rated current passes through it. When the current passing through the fuse exceeds the rated current, the thin wire melts and breaks the circuit.
The glass fuses commonly come in various types:

Fast Blow
Normal
Slow blow

Glass fuse does not contain any gas AFAIK. The glass tube protects the outside environment when the metal inside melts as high temperature can build up. Glass being transparent, helps to visually inspect the fuse to make sure if it is blown.

Automotive

Used in older-model cars, glass tube fuses today are found primarily in automotive accessory applications. The expansive Aolittel line of glass fuses includes many types and sizes in addition to those listed in this catalog. Contact Aolittel for more product details if you have requirements which are not covered here.

Appliances and Consumer Electronics

Glass and ceramic tube uses are often used to protect appliances and consumer electronics. As electronic equipment becomes smaller, the circuits and components become more delicate and easily damaged. Fuses are the preferred method of protection due to their accuracy, small size and reliability. Fuses are available in a wide variety of amp ratings to provide precise protection. Generally, two sizes of user-replaceable fuses are found: the 1/4” x 11/4” and 5 x 20mm. Each is available in a variety of volt and amp ratings.

Fuse Types

There are two basic types of fuses available for appliances and consumer electronics: fast-acting or time-delay. Any replacement fuse must match the one it’s replacing. In general, fast-acting fuses are a single strand of wire or strip of metal. Time-delay fuses usually have a coiled wire, a thick element wrapped in wire, or a spring. Most electronic fuses will have the voltage and amp rating stamped on the end cap. The type of fuse can generally be visually identified. Also, owner’s manuals will have the correct replacement fuse generically identified. For example: “Use a 2 amp, time-delay, 250 volt fuse.”

Fuse Selection Criteria

For electronic/electrical applications, fuse must be rated at 125V or better.
Voltage must match or exceed the fuse being replaced (125V for household current; 12V for auto; 24V for heavy duty).
Fuse must match required fuse characteristic – either fast-acting or time-delay.
Amp rating must match that of the original fuse.

A Note on Voltage Rating

All fuses have a voltage rating. To maintain safety, this voltage rating should not be exceeded in application, although it is acceptable to use a higher rated fuse in a lower voltage application. For example: A fuse rated for 125 volts is appropriate in household (110V) or automotive (12V), while a fuse rated for 32 volts is appropriate for automotive (12V), but not for household (125V). Always replace a fuse with one of the same or higher voltage rating.
