Bussmann KRP-CL-400 Class L High Current Fuse

The Bussmann HI-CAP KRP-CL-400 is a 400 A, 600 V AC current-limiting, time-delay cartridge fuse in a cylindrical body designed for bolt-down mounting. As part of the KRP-CL Class L family, it delivers high interrupting capacity with a 200 kA rating at 600 VAC and is specified as a slow-blow (time-delay) fuse, ideal for circuits with brief overloads or inrush currents. The fuse measures 2.500 inches in diameter by 3.750 inches in length and uses bolt terminals for secure installation, with a cartridge-style construction that fits Bussmann’s HI-CAP current-limiting lineup. This specific KRP-CL-400 model is categorized under Class L protection and is commonly referenced for electrical and industrial applications requiring robust high-current protection in a compact, boltable package. Manufactured under the Bussmann name (a division of Eaton), the KRP-CL-400 is designed to balance rapid fault interruption with controlled let-through for high-current systems, providing reliable protection for power distribution cabinets, transformers, and other heavy-duty equipment.
