The 2AG Slo-Blo
fuses are available in cartridge form or with axial
leads. Axial leaded fuses are board washable. 2AG fuses provide the
same performance characteristics as their 3AG counterpart, while
occupying one-third the space. Sleeved fuses are available.

The 2AG Indicating Slo-Blo
fuse instantly identifies itself upon
opening by showing a discoloration of its glass body. Guesswork
and time consuming circuit testing are eliminated. This unique
design offers the same quality performance characteristics as
the standard 2AG fuse design.
* When ordering the 2AG Indicating Slo-Blo Fuse, an `S' is
required after the catalog number.
