Series
Compact Fused Switch Class J
The Mersen FS Series is a UL 98 Listed fused disconnect switch designed for branch circuit protection using any UL Listed Class J fuse. Engineered for performance and convenience, the FS Series delivers the high interrupting capacity of Class J fuses (200kA SCCR) in the same footprint of a fuse holder. It occupies less space than a standard fuse holder and traditional disconnect switch combination, enabling more streamlined panel designs and improved off-the-shelf distribution availability when time and convenience matter most. Available in 30A and 60A versions, the FS Series includes lockout/tagout (LOTO) capability and integrated LED fuse status indication.
