| Datasheet | Download Datasheet |
The Mersen / Ferraz Shawmut A2K175R is a 175 A fast-acting UL Class RK1 fuse, rated 250 V AC, 250 V DC (DC self-certified).
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 AC, 20 kA DC.
Construction: 1-9/16 in (40 mm) x 7-1/8 in (181 mm) diameter x length; knife blade with mounting hole and rejection slot.
It is UL Listed and CSA Certified.
