Class J Fuse Disconnect Switches

Littelfuse Class J Fuse Disconnect Switches combine multiple fuses and a switch into a single, compact device with front or side operation. These switches provide a simple way to manually open and close a circuit while protecting against short circuits and overcurrent. The double-break contact system breaks the circuit both upstream and downstream, allowing the switch to handle higher voltages and delivering a longer switch life. The modules offer fuse isolation to easily segregate a particular fuse on the circuit for repair or maintenance. Littelfuse Class J Fuse Disconnect Switches have a small footprint, 600V rated voltage, and a choice of 30A, 60A, 100A, or 200A with neutral, no neutral, or detachable neutral options. The lineup includes accessories such as handles, auxiliary contacts, terminal shrouds and lugs, phase barriers, and key-lock devices. Applications include industrial, HVAC/R, mining, solar, and battery energy storage systems (BESS).
