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.
