Fuse Amp-Trap 2000® 600V 400A Time-Delay Class J AJT Series Smart-Spot

Fuse Amp-Trap 2000® 600V 400A Time-Delay Class J AJT Series Smart-Spot The Amp-Trap 2000® AJT fuse is designed for reliable protection of motor circuits, mains feeders, branch circuits, lighting, heating, and general loads. It is suitable for transformers, control panels, circuit breaker back-up, bus duct, and load centers. This time-delay fuse provides IEC Type 2 no damage protection while requiring half the mounting space of traditional 600VAC Class RK fuses. Its SmartSpot visual open fuse indicator enhances maintenance efficiency, and its time-delay characteristics accommodate motor and transformer inrush currents with superior current-limiting capability.
