Amp-Trap 2000 time-delay AJT fuses provide 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 600V UL Class RK fuses. Time-delay characteristics handle motor in-rush currents without nuisance trips. Its current-limiting ability and wide range of ratings provide excellent overcurrent protection for all your applications. An optional mechanical blown fuse indicator and Microswitch is available on blade-type (70 to 600A) fuses for visual and/or remote blown fuse indication. Solid-state SmartSpot indicator, Time-delay for motor starting and transformer inrush, 300kA interrupting rating, self-certified (UL witnessed), Extremely current-limiting for low peak let-thru current, Most current-limiting UL class fuse, Small footprint requires less mounting space and allows smaller, more economical fuse blocks, Easy 2-to-1 selectivity for prevention of nuisance shutdowns, Unique Class J dimensions prevent replacement errors, High-visibility orange label gives instant recognition, Metal embossed date and catalog number for traceability and lasting identification, Fiberglass body provides dimensional stability in harsh industrial settings, High-grade silica filler ensures fast arc quenching. Application Motor Circuits, Mains, Feeders, Branch Circuits, Lighting, Heaters, Transformers, Control Panels, Circuit Breaker Back-up, Bus Duct, Load Centers.
