BUSSMANN CableLimiter Fast-Acting K

Cable-to-cable limiter fuses are current-limiting protective devices designed to isolate individual conductors in low-voltage electrical systems where both ends of the limiter connect directly to cables. These limiters are commonly used in underground distribution networks, service entrances, and multi-conductor installations where space constraints or layout requirements prevent bolted connections. Their primary role is to rapidly interrupt high fault currents, protecting cables and downstream equipment from thermal and mechanical damage. Like other limiter types, they are not rated for overload protection but are selected based on the cable size they protect. Their fully cable-connected design makes them ideal for flexible, in-line installations in commercial, industrial, and utility applications.
