What is an AB or AG fuse?:

Many fuse sizes began with the early “Automobile Glass” fuses, with the erm “AG”. Numbers were applied chronologically as manufacturers made a new size available: “3AG,” for example, was the third size placed on the market. Other non-glass fuse sizes and materials were determined by functional requirements, but they still retained the length or diameter dimensions of the glass fuses. Their designation was modified to AB in place of AG, indicating that the outer tube was constructed from Bakelite, fiber, ceramic, or material other than glass.

Ceramic Fuse Compatibility

It has been found that some equipment with no inrush protection may destroy Ceramic body fuses. It is recommended that a potential fuse customer first try a stock ceramic body fuse before ordering the Acme Fuses.

 CFC - Formerly known as "Special Sauce"

Crystal Fiber Compound is the name given to the coating available on several Acme Products. It is a combination of materials designed to improve sonic performance.
