The KLKR Series fast-acting fuses are designed for general-purpose branch circuit protection. Their compact size, fast-acting overload response, and current-limiting design make them ideal for use in OEM equipment and control panels. They are widely used in lighting circuits and control transformer circuits where a fast overload response is required. These KLKR Series Class CC fuses have rejection features that prevent substitution of lower rated fuses. Due to their compact size, these fuses provide superior branch circuit protection in a fraction of the space required by other fuse classes. The KLKR Series fuses comply with UL and CSA standards. Fast-acting Provides protection for equipment requiring fast overload protection Current-limiting Reduces damage caused by heating and magnetic effects of shortcircuit currents Rejection capability Prevents use of fuses with lower interrupting ratings or voltage whenused with corresponding fuse holders 200,000 AIR Smallest 600 V, 200,000 A fuse approved for branch circuit protection Applications • Control circuits • General loads • Branch circuit protection • Solid-state components Ampere Rating (A) 1 VAC (V) 600 VDC (V) 300 Interrupting Rating 200 kA @ 600 Vac Opening Fast-Acting (F) Size Class CC
