The KLC series is a traditional North American-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 600 V ac. This is a round body, extremely current-limiting fuse for use where no time delay is required. It is typically used for replacement purposes only. For new designs, the L70QS series is recommended.
POWR-SPEED® brand fuses are optimized for performance and efficiency to help extend equipment life. They offer Littelfuse-developed technology that sets tomorrow’s standards for accuracy, consistent quality, reliability, and predictable performance. Littelfuse engineers have redefined high-speed fuse technology by using advanced metallurgical, polymer, and materials research, mathematical modeling, and computerized statistical analysis.
The KLC series is specifically designed for supplementary protection of semiconducting devices such as silicon controlled rectifiers (SCRs), diodes, thyristors, triacs, transistors, and similar solid-state devices. These devices are used in power equipment including variable speed drives, power rectifiers, UPS systems, dc power supplies, and in a wide range of electronic equipment.
