3AB Cartridge Fuse
Data Sheets »

The 3AB cartridge fuses are miniature electronic fuses having a diameter of 1/4 inch and a length of 1-1/4 inches and are very common in North America. The 3AB fuse is designed with a ceramic body which can tolerate higher temperatures and offers higher interrupting and voltage ratings than the 3AG fuse. Ratings are typically provided at both 125 and 250 volts AC. Fuses rated up to 500 volts are available. The 3AB fuse type is offered in fast acting or time delay versions and can be ordered with or without axial leads. A pin indicator version that provides visual indication of a blown fuse or alarm circuit activation is also available. They are typically built in accordance with UL 248-14 and CSA C22.2/No. 248.14 standards. Fuses with these dimensions and construction type are also offered under the BSI - Britain and JIS - Japan standards.

Littelfuse, Bussmann and Schurter offer 3AB fuses.
