Bussmann by Eaton KRP-C-800 Class L Fuse High Current

The Bussmann by Eaton KRP-C-800 Class L fuse is a high-current, current-limiting time-delay device rated for 800 A at 600 V AC (and 300 V DC), designed for demanding power circuits in industrial equipment. This Low-Peak Class L fuse from the KRP-C family features a time-delay, current-limiting action that balances fast short-circuit interruption with reduced let-through, offering interrupting ratings up to 300 kA at 600 VAC and 100 kA at 300 VDC. It uses a bolt-on body for secure mounting on panels or switchgear, and is commonly cataloged as KRP-C-800SP. The 600 VAC rating makes it suitable for mains-powered distribution and motor feeders, while the 300 V DC rating supports DC bus and drive applications in rugged industrial environments. In practice, it protects large power circuits and equipment by clearing faults quickly and limiting arc energy, aligning with Eaton Bussmann Series Class L performance. Typical fuse blocks in the 601–1200 A range compatible with KRP-C fuses are recommended for this ampacity class.
