- The Bussmann CC-TRONŽ (FNQ-R) was designed to meet the needs of
control circuit transformer protection.
- Current-limitation protects down stream components against damaging
thermal and magnetic effects of short-circuit currents.
- Rejection feature - FNQ-R fuses meet the U.L.
508,paragraph 19.2.4 requirement that control circuit fuses used in equipment listed for
use with more than 10,000 ampere available must have an adequate interrupting rating and
must be rejection type.
- 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 U.L. requirements and still allow the high
inrush currents, with significantly more time-delay than the U.L. minimum value of 12
seconds at 200% for Class CC fuses.
- Melamine tube. Albaloy-plated brass endcaps.
