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.
