General Purpose US US Fuses General Purpose Fuses American Power Fuses AMP-TRAP 2000 AJT (Class J TD) (R) SMARTSPOT(R) with Maximum circuit protection Amp-trap 2000(R) SmartSpot(R) AJT fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line the AJT fuse provides IEC Type "2" (No Damage) protection to main, feeder, and branch circuits, for all types of loads -- yet, they require only half the mounting space needed for 600VAC Class RK fuses. AJT's time delay characteristics for handling typical in-rush currents, its current limiting ability.
