CLASS CC KLKR SERIES FUSES
600 VAC • 300 VDC • Fast-Acting • 1/10-30 A
Description
KLKR Series Class CC fuses are fast-acting fuses intended
for general purpose branch circuit protection. Their compact
size, fast-acting overload response, and highly currentlimiting design make them ideal for use in OEM equipment
and control panels.
Features/Benefits
• Meets UL and CSA standards
• Class CC fuses are the smallest 600 V, 200,000 A.I.R.
fuses approved for branch circuit protection
• Rejection feature prevents use of fuses with lower
interrupting ratings or voltage ratings when used with
corresponding fuse holders
• Extremely current limiting reduces damage caused by
heating and magnetic effects of short-circuit currents
