Switch functionality with high protection level

Mersen’s FS Series UL 98 Listed fused disconnect switch is 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. Occupying less space than a standard fuse holder and traditional disconnect switch combination, it enables more streamlined panel designs, ease of installation, and improved off-the-shelf distribution availability when time and convenience matter most, making it a suitable choice for panel builders. Available in 30A and 60A versions, the FS Series Class J Fused Switch includes lockout/tagout (LOTO) capability and integrated LED fuse status indication and comes with an IP20 rating. It features a smaller footprint compared to a traditional Class J disconnect with a max interrupting rating of 200kA. The Class J Fused Switch is UL 98 listed and suitable for use as a main/feeder device. Designed to accept ALL standard 30A and 60A Class J fuses, Mersen’s Class J Fused Switch gives panel builders flexibility in fuse manufacturer selection and an all-important space saving option when compared to standard fused disconnects.
