Bussmann KRP-C-1200 Hi-Cap High Interrupting Capacity Fuse

Bussmann KRP-C-1200 Hi-Cap is a Low-Peak time-delay, current-limiting fuse rated for high-capacity mains and feeders, with a 1,200 A capacity and a operating range of 600 VAC / 300 VDC. It delivers a 300 kA RMS symmetrical interrupting rating at 600 VAC and 100 kA RMS at 300 VDC, providing robust short-circuit protection in power distribution panels and large feeders. This KRP-C family fuse uses a cartridge-body construction with bolt-on mounting and knife-blade terminals, aligning with UL-listed Low-Peak KRP-C specifications for time-delay, current-limiting protection. Typical physical form factor is approximately 10.75 inches long and 2.5 inches in diameter, designed to fit standard high-capacity fuse blocks in industrial settings. The device is intended to clear faults quickly (about 4 seconds under overload conditions in typical applications), enabling selective coordination in systems where fast fault clearance is essential without unnecessary outages, making it suitable for mains, large switchgear, and industrial equipment protection. Its Hi-Cap rating and class L designation position it as a high-interrupting-capacity option within the Bussmann line for demanding power distribution environments.
