Amp-Trap 2000® ATDR small-dimension fuses can provide IEC Type 2
No Damage protection to your facility’s increasingly sensitive branch
circuit components and small motors – minimizing the risk of fault-
related damage. ATDR Class CC fuses deliver the best time-delay
characteristics in their class with excellent cycling ability for small
motor loads.
FEATURES/BENEFITS:
• Time-delay for motor starting inrush currents without nuisance
opening
• Highly current-limiting for low peak let-thru current
• Improved cycling ability for frequent motor starts/stops without
nuisance fuse opening
• Rejection-style design prevents replacement errors (when used
with recommended fuse blocks)
• High-visibility orange label ensures instant brand recognition,
simplifies replacement
• 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 and optimum
current-limitation
