KTS-R-400 - 400 Amp Fuse

KTS-R-400 - 400 Amp Fuse

At 400 amps, you want a replacement fuse that matches specifications, specification by specification. The Eaton Bussmann KTS-R-400 is a 400A Class RK1 fuse rated for 600V, with an interrupt rating of 200 kAIC at 600 Vac. Its physical construction includes a melamine glass tube, one element, and a blade-end-to-blade-end connection, while the manufacturer lists a knife blade as a special feature. Whether you're checking an existing KTS-R-400 or working from equipment documentation, having the electrical ratings, connection style, dimensions, and fuse class together makes the replacement comparison much more straightforward.

Where It Works Best

The Eaton Bussmann KTS-R-400 is a product to check against equipment documentation specifying a 400A, 600V, Class RK1 fuse with a 200 kAIC interrupt rating at 600 Vac. The blade-end-to-blade-end connection and 11.63 x 2 x 2-inch dimensions are equally important checkpoints, especially when you're replacing an existing fuse and need the physical configuration to match.
