- Time-delay for motor starting and transformer inrush
- Extremely current limiting for low-peak let-thru current
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. 60 ampere current rating. Measures 1-1/16-inches diameter by
