SLO-BLO GLASS INDICA H-PACK 3A. The 3AG Slo-Blo® fuse solves a broad range of application requirements while offering reliable performance and costeffective circuit protection. Features: 313 and 315 series fuses have time-delayed in the overload range, which provides superior protection inductive loads such as motors, transformers, and solenoids. 3AG indicating fuses instantly identify themselves upon opening by showing a discoloration of their glass bodies. Guesswork and time-consuming circuit testing is eliminated. This unique design offers the same quality performance characteristics as the standard 3AG fuse design.
