November 23, 2023 – Littelfuse’s Class J fuse disconnect switch combines a switch and multiple fuses into a single product offering, promising a simpler way to manually open and close a circuit.

When the switch detects an overload or short circuit, the fuse blows automatically to open or break the circuit—both upstream and downstream—and shut off the equipment. The 600V switch is available in 30A, 60A, 100A, and 200A.

The switch sports “safe-to-touch” transparent fuse covers that cannot be opened when in the ON position for added protection. It comes with horizontal, vertical or 45-deg mounting options, and optional handles with front or side operation to accommodate system design.

Applications include HVAC/R, mining, solar photovoltaic, energy storage, and industrial.
