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. Ideal Applications include: Industrial control panels, Data centers, Main disconnects, Motor branch circuit protection, Fused Coordination Panels, For use as a motor disconnect, see horsepower rating section
Features & Benefits:
- Smaller footprint compared to a traditional Class J disconnect
- Accepts Class J 30A and 60A fuses for branch circuit protection
- 35mm DIN rail mounted
- Built-in lockout/tagout feature
- Integrated LED Fuse status indication
- 200kA SCCR rating
- 75°C CU Wire
- Factory & Field Wiring
- Minimum Indicator Voltage – 90V-AC and 12V-DC
Mersen’s CMC10 fuse holders are finger-safe under IEC standards with an IP20 grade protection. Fuses can be changed safely by hand with ease under these conditions.
The modular fuse holders are available in one, two, three or four poles with or without a visual blown fuse indicator. The Modulostar line features durable thermoplastic or thermoset materials and are lockable without any additional kit.
The fuse holders are engineered for use in all circuits up to 690 V for protection of motors, transformers, low voltage distribution, control circuits, drive protection and metering in marine, railway and non-load operation applications.
