The new compact Class J Fuse Disconnect Switch from Littelfuse, Inc., combines a switch and multiple fuses into a single product offering a simpler way to manually open and close a circuit while safeguarding against overcurrent and short circuits. When the switch detects an overload or short circuit, the fuse blows automatically to open or break the circuit both upstream and downstream and shuts off the equipment. The 600 V switch is available in 30 A, 60 A, 100 A and 200 A and protects many applications in various industries including HVAC/R, mining, solar and energy storage.
"When installing or maintaining equipment, the Class J Fuse Disconnect Switch makes it both safer and easier to connect or disconnect the power in an isolated area,” stated Augusto Sanchez, Littelfuse industrial business product manager. “In addition, with a higher interrupting rating, the switch delivers more robust

The Class J Fuse Disconnect Switch features a small footprint to save space and provide design flexibility, and a no-tools-required frontal direct handle for easy and quick installation. Additional design advances include safe-to-touch transparent fuse covers that cannot be opened in the “ON” position for extra protection while providing visibility to fuses — without opening the module — for added convenience.
Horizontal, vertical or 45° switch mounting options enhance installation adaptability while optional handles with front or side operation accommodate system design. An optional lockout-tagout padlock can be added when the device is in the “OFF” position to ensure equipment is properly shut off during maintenance or repair to prevent the release of hazardous energy safeguarding personnel and equipment.
