373 and 375 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.
