APPROVALS & STANDARDS AJT (1-600): UL listed to standard 248-8 File E2137 DC listed to UL standard 248 CSA certified to standard C22.2 No. 248.8 IEC 60269-2-1 AJT (70-600) EI: UL listed DC tested to UL standard 248 KEY FEATURES & BENEFITS 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 Most current-limiting UL class fuse 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 industrial settings High-grade silica filler ensures fast arc quenching Optional EI indicator/switch mount for AJT70 to 600 open fuse indication APPLICATIONS Motor circuits Mains Feeders Branch circuits Lighting, heating & general loads Transformers Control panels Circuit breaker back-up Bus duct Load centers Item Number AJT125N Item Description (ERP) 600VAC 125A CLASS J TD FUSE Short Description Fuse Amp-Trap 2000® 600VAC 125A Time-Delay Class J AJT Series EAN/UPC Code 782001497842 Rated voltage AC UL 600 V Rated voltage DC UL 500 V Frequency 50/60 Hz Ampere Rating 125 A ROHS Compliant Yes Fuse Class Class J Speed/Characteristic Time Delay Mounting Clip or Bolted AC Max I.R./Breaking Capacity: I1 200 kA Contact materials Brass Connection/Terminal Type Blade Body/Insulating Material GMG
