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 600 VAC 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.
