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
Applications
•General purpose protections for equipment requiring fast overload protection
