The Littelfuse KLNR500 is a 500 A fast-acting UL Class RK1 fuse, rated 250 VAC / 125 VDC.
Class RK1 is the most current-limiting Class R branch-circuit fuse: it fits the same rejection-type Class R holders as an RK5 but lets through less fault energy. A fast-acting fuse opens quickly on an overload, for resistive and lightly loaded circuits with little switch-on surge.
Interrupting rating: 200 kA @ 250 VAC; 20 kA @ 125 VDC (Littelfuse self-certified).
Construction: 263.5 mm overall length; knife blade with rejection notch.
It is UL Listed and CSA certified (UL file E81895). Standards: UL 248-12.
