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, 60, 100, and 200 A and protects many applications in various industries including HVAC/R, mining, solar, energy storage, and industrial.

"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 protection, increases personnel safety and offers a longer switch life."
