Bussmann KTK-5 Industrial Grade Fast Acting Cartridge Fuse

KTK-5 is an industrial-grade, fast-acting cartridge fuse from Bussmann (Eaton) in the Limitron family, rated for 5 A at 600 V AC. This non-indicating fuse uses a melamine tube with nickel-plated bronze endcaps and ferrule-end terminations, measuring 1-1/2 in (38.1 mm) long and 13/32 in (10.3 mm) in diameter, and it provides up to 100 kA interrupting capacity at 600 V AC. The device is designed for control circuits, lighting circuits, metering, and other panel-protection roles in industrial equipment; it is compatible with standard Bussmann KTK holders and ferrule-end circuitry. The KTK-5 is a compact, single-element fuse suitable for inline or panel-mount protection where a 5 A, 600 VAC fast-acting fuse is specified, making it a common choice for protecting small control transformers, relays, and instrumentation in industrial cabinets. With its 1.5-inch length and ferrule-end design, it fits typical midget-fuse footprints and provides reliable protection in crowded electrical enclosures while maintaining high short-circuit withstand in demanding environments.
