The Bussmann KTS-R-150 is a current-limiting, fast-acting Limitron fuse in the RK1 class designed for low-voltage protection up to 600 V. It is rated for 150 A with a 200 kA interrupting rating at 600 V, providing rapid clearance of high-fault currents in power distribution circuits. The device features a cylindrical cartridge body with ceramic construction and measures about 1.50 inches in diameter and 9.63 inches long. As a rejection-style fuse, it helps prevent incorrect RK1-type substitutions in panel-fuse slots and is typically used in industrial control panels and feeder protection where fast, reliable overcurrent protection is required.
