Bussmann DLS-R-300 - RK5 Class Fuse 300A (200kA AIC @ 600V)

Bussmann DLS-R-300 is a current-limiting fuse from the Dura-Lag family designed to provide reliable overcurrent protection in low voltage electrical systems. It features a 300A current rating and a 600V AC voltage rating, engineered to safely interrupt fault currents up to 200kA at its rated voltage. The fuse is constructed as a single-barrel unit with an RK5 class rating, indicating a high degree of current limitation and a time-delay characteristic to prevent nuisance tripping on harmless temporary overloads. It is built to meet applicable industry standards for safety and performance in demanding industrial environments. Typical applications include the protection of motor circuits, feeders, and branch circuits in industrial control panels, switchgear, and distribution equipment.
