Axial Lead & Cartridge Fuses
313/315 Series
Lead-Free 3AG, Slo-Blo
®
Fuse
PS

Description
The 3AG Slo-Blo
®
fuse solves a broad range of application
requirements while offering reliable performance and cost-
effective circuit protection.
The fuse catalog number with the suffix “ID” 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 3AG
Slo-Blo
®
Fuse design.
