- Additional DetailsAmp-Trap 2000® SmartSpot AJT fuses now provide a visual open fuse indicator. With advanced material technology the AJT fuse provides IEC Type 2 No Damage protection to main, feeder, and branch circuits, for all types of loads. They require only half the mounting space needed for 600VAC class RK fuses. AJT’s time delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current limiting ability.
