Long Description Amp-Trap 2000 AJT fuses provide non-indication as well as a SmartSpot 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 yet, they require only half the mounting space needed for 600VAC Class RK fuses. AJTs time-delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current-limiting ability.
