The KTK-10 is a 10 A LIMITRON fast-acting cartridge fuse in a 10 mm × 38 mm format, designed for 600 V circuits. Manufactured under the Bussmann name (Cooper Bussmann), it features ferrule-end terminations with nickel-plated bronze endcaps and a melamine tube, and it carries a 100 kAIC interrupting rating at 600 V. This non-indicating fuse protects control circuits, lighting circuits, and metering applications in industrial and electrical systems by responding quickly to overcurrents, helping prevent damage from short circuits or overloads.
