229/230 Series
229/230 Series Lead-Free 2AG, Slo-Blo® Fuse and Indicating Slo-Blo® Fuse
The 2AG Slo-Blo® Fuses are available in cartridge form or
with axial leads. 2AG Fuses provide the same performance
characteristics as their 3AG counterpart, while occupying
one-third the space.
The fuse catalog number with the sufx “S” instantly
identies 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
Slo-Blo® fuse design. When ordering the 2AG Indicating
Slo-Blo® Fuse, an 'S' is required after the catalog number.
