Fuse Amp-Trap 2000® 600V 300A Time-Delay Class J AJT Series

The Amp-Trap 2000® AJT fuse is designed for reliable protection of motor circuits, mains feeders, branch circuits, lighting, heating, general loads, transformers, control panels, circuit breaker backup, bus duct, and load centers. This Class J time-delay fuse offers IEC Type 2 no damage protection with advanced material technology, providing superior current-limiting capability while occupying half the mounting space of comparable 600VAC Class RK fuses. Its time-delay characteristics are optimized for motor and transformer inrush currents, making it suitable for demanding electrical distributor and switchgear supplier applications.
