Mersen RK1 Reducer Fuses

Mersen is the only manufacturer that offers reducer fuses. Reduce current rated fuses that are designed to fit into the next larger size fuse holders. Mersen reducer fuses provide the same highly reliability, durability, performance, and arc flash mitigation as standard Class RK1 or Class J fuses. They are ideally suited for start up or newly expanded manufacturing facilities that are ramping up production and electrical power demand. Upon approaching full capacity, the reduced rating reducer fuses can be easily replaced by higher standard rating fuses of the same body size eliminating the need to use a fuse reducer accessory.
