AJT50 Fuse - Time-Delay - Class J

600 Volt - 50 Amp - 200kA I.R. AC - 10 Pack - Mersen


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.
