Cooper-Bussmann by Eaton KRP-C-1200 Class L Fuse

The Cooper-Bussmann by Eaton KRP-C-1200SP Class L fuse is a high-current, current-limiting time-delay device designed for 600 VAC systems, capable of withstanding large surge events while protecting downstream equipment. As part of the KRP-C Class L family, it is rated at 1200 A with an interrupting rating of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC. The fuse employs Low-Peak time-delay technology to offer selective protection for circuits where short, high-current faults are possible, reducing nuisance blows in normal operation. The KRP-C-1200SP variant is documented by Eaton/Bussmann as a Class L, current-limiting fuse with a 600 VAC/300 VDC rating and is widely referenced in major catalogs and distributors for heavy-duty power distribution applications up to 1.2 kA.
