MERSEN AJT1-12N AJT1-1/2N

Amp-Trap 2000® AJT fuses provide non-indication as well as a SmartSpot® visual open fuse indicator. With advanced material technology the AJT fuse provides 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 600VAC Class RK fuses. AJT’s time-delay characteristics are ideal for handling typical motor and transformer inrush currents, while also providing superior current-limiting ability. Non-indicating or solid state SmartSpot visual blown fuse indicator. Time-delay for motor starting and transformer inrush. 300kA interrupting rating - self-certified, UL witnessed tests. Extremely current-limiting for low peak let-thru current. Non-indicating fuses suitable for use in NEC Class I Division 2 hazardous locations1. Recommended for Arc Flash energy reduction. 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 brand recognition. Metal-embossed date and catalog number for traceability and lasting identification. Fiberglass body provides dimensional stability in harsh environments. High-grade silica filler ensures fast arc quenching. Optional EI open fuse indicator/switch mount for AJT70 to 600.
