Bussmann KTS-200 Limitron Class K1 Fast Acting Fuse

Bussmann Limitron KTS-R-200 fast-acting fuse, Class RK1, provides 200 A of current-limiting protection for 600 V AC circuits, delivering fast fault clearance with minimal let-through energy. This non-indicating device is designed to fit RK1 fuse blocks and standard switches that accept RK1 fuses, enabling straightforward replacement in existing Bussmann installations and ensuring compatibility across the Eaton Bussmann series. With an interrupting rating of up to 200 kA at 600 VAC, it is engineered to safely interrupt high fault currents in industrial environments while maintaining a compact form factor suitable for crowded control panels. As part of the Limitron lineup, the KTS-R-200 is a current-limiting fast-acting solution ideal for protecting branch circuits in industrial control panels, power distribution gear, and machinery that rely on rapid fault isolation. This fuse represents a robust, high-current option within Bussmann’s RK1 family, pairing with common holders and mounting arrangements used in electrical panels and distributed power systems.
