Class T Fuses
At less than one-third the size of similarly performing Class R fuses, current-limiting POWR-GARD® Class T fuses offer space-saving overcurrent and short-circuit protection solutions in applications requiring fuses with current ratings higher than 30 A. Be aware, however, that Class T fuses may provide protection only against short circuits when used with circuits carrying inductive loads. For applications where fuse size is not a principal concern, Littelfuse recommends JTD_ID series Class J fuses, LLRNK or LLSRK Class RK1 series fuses, or FLSR_ID series Class RK5 fuses.
  • Fast-acting
  • Current ratings from 1 A to 1.2 kA
  • Interrupting ratings up to 200 kA at 1.2 V ac and 200 kA at 200 V dc
  • RoHS compliant
  • Work in ac and dc systems
  • NEC-compliant overcurrent and short-circuit protection solution when used with circuits carrying noninductive loads
  • Current-limiting performance reduces magnetic effects and heat damage from short circuits
  • Use with input or output circuits for surge-sensitive components can prevent the opening of semiconductor fuses for those components
  • Blade, cartridge, and surface mount configurations available
