KLKR series Class CC fuses are fast-acting fuses intended for
general-purpose branch circuit protection. Their compact size,
fast-acting overload response, and their highly current limiting design
make them ideal for use in OEM equipment and control panels because
Solid-state devices such as SCRs and other electronic equipment
generally require fast-acting protection.
Compared to other UL Listed fuses, Class CC fuses are the most current limiting, rating for rating.
Provide superior protection in a fraction of
the space required by other fuse classes. For example, when 600 V
three-pole, 30 A Class R fuse blocks are replaced by Littelfuse Class CC
fuse blocks, panel-mounting space is reduced approximately 70%.
Applications:
General purpose protection of equipment requiring fast overload
protection – KLKR series, fast-acting fuses used for protection of
equipment containing solid-state devices or other electronic components
requiring fast response on overloads.
Safety:
200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes.
Extremely current limiting — Reduces damage
caused by heating and magnetic effects of short-circuit currents…stops
damaging short-circuit faster than any mechanical protective device.
Space Saving:
Class CC fuses are the smallest 600V, 200,000 A.I.R. fuses approved for branch circuit protection.
