  • 229 series 2AG fuses have time-delay of 313 series 3AG fuses in less than one-third of the space.
  • They provide superior protection for inductive loads such as motors, transformers, and solenoids.
  • Use whenever time-delay fuses are indicated.
  • An indicating version is also available. 2AG 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 2AG fuse design.
