Fuse Amp-Trap 2000® 600V 90A Time-Delay Class J AJT Series Smart-Spot

The Fuse Amp-Trap 2000® AJT Series provides advanced time-delay protection for motor circuits, mains feeders, branch circuits, lighting, heating, transformers, control panels, circuit breaker back-up, bus ducts, and load centers. This Class J fuse is designed with SmartSpot visual open fuse indication and offers IEC Type 2 no damage protection. Its compact size requires only half the mounting space of traditional 600VAC Class RK fuses. The AJT fuse’s time-delay characteristics are optimized for handling motor and transformer inrush currents while delivering superior current-limiting performance. Ideal for electrical distributors and switchgear suppliers focusing on reliable circuit protection and efficient lighting solutions.
