MIL
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.

2AG Indicating Slo-Blo^® Type Fuse
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.
Example:
-1A Indicating Slo-Blo^® Fuse = 230 001S
NOTE: LF logo, series number, amperage rating, voltage rating, and UL and CSA logos are
stamped on the fuse caps.
