10X better current limitation than basic circuit breakers and non-
current limiting fuses helps prevent damage caused by short-

Incorporates Class R rejection feature. Installation in a rejection
base fuse block is recommended as it helps prevent a lesser-
rated fuse from being installed. However, both KWN-R and
KWS-R fuses can be inserted in non-rejection type fuse holders
to physically and electrically replace fast-acting Class H, RK1, K5,
RK5 and other fast-acting fuses.
