Mersen AJT Amp-Trap 2000 SmartSpot Time-Delay/Class J Fuse with Maximum Circuit Protection, 600VAC/500VDC, 200kA AC/100kA DC, 40 Ampere, 1-1/16"Diameter x 2-3/8" Length

Mersen AJT Amp-Trap 2000 SmartSpot time-delay/class J fuse with maximum circuit protection. It provide a 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. 300kA interrupting rating - self-certified, UL witnessed tests. 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. Use for motor circuits; mains; feeders; branch circuits; lighting, heating and general loads; transformers; control panels; circuit breaker back-up; bus duct and load centers. Approvals: UL listed to standard 248-8 file E2137, DC listed to UL standard 248, CSA certified to standard C22.2 No. 248.8, IEC 269-2-1. 600VAC/500VDC voltage rating. 200kA AC/100kA DC IR rating. 40 ampere current rating. Measures 1-1/16-inches diameter by 2-3/8-inches length.

• Solid state SmartSpot visual blown fuse indicator
• Time-delay for motor starting and transformer inrush
• Extremely current-limiting for low peak let-thru current
• Most current-limiting UL class fuse
• Recommended for arc flash energy reduction
