Dimensional Data

General Information:

the needs of control circuit transformer protection.

• Current-limitation protects down stream components

against damaging thermal and magnetic effects of short-

circuit currents.

• High inrush time-delay. Control circuit transformers can

experience inrush currents up to 85 times their full-load

current rating. FNQ-R fuses can be sized according to

NEC and UL requirements and still allow the high inrush

currents, with significantly more time-delay than the UL

minimum value of 12 seconds at 200% for Class CC fuses.

• Melamine tube. Nickel-plated brass endcaps.
