An RK1 fuse is a subclass of Class R fuses. Considered as a current limiting fuse, an RK1 can efficiently disrupt a minimum of 200,000A flow. Some RK1 fuses
have as much as 300,000A interrupting rating. Depending on the equipment and application, you can get an RK1 fuse as fast-acting or time-delay. Purchase Bussmann RK1 fuses at MRO Supply.
