Take control of fault currents headed
for your control transformer
ATQR small-dimension fuses feature time delay
characteristics ideally suited for the high inrush
currents of control transformers, solenoids, and similar
inductive loads. The newest member of our Amp-trap
2000® family of fuses - ATQR fuses
provide superior protection for the branch circuits of elec-
trical distribution systems.
Features/Benefits
• Time delay for control transformer inrush loads without
nuisance opening
• Highly current limiting for low peak let-thru current
• Rejection-style design prevents replacement errors
(when used with recommended fuse blocks)
• High-visibility orange label ensures instant recognition,
and 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
high current limitation
Ratings
AC: 1/10 to 30A 600VAC, 200kA I.R.

Recommended Fuse Blocks for Class CC Fuses
Primary fuses - If primary FLA is less than 2 amps, fuse may be 300%
max. (500% for motor control). If primary FLA exceeds 2 amps but is
less than 9 amps, fuse may not exceed 167% of primary FLA unless
secondary protection is used, when it may be increased to 250%.
Fuse sizes shown are based on approx. 40 x FLA for .01 sec.
