Switches and disconnects

Fusible panelboard and switchboard switches

Fusible panelboard and switchboard switches are designed with quick-make, quick-break mechanisms and are enclosed for installation in specific panelboard and switchboard designs. They have a maximum interrupting capacity of 200 kAIC at 600 Vac and are rated for 100% load break and load make - the continuous load current should not exceed 80% of the fuse ratings. Each switch includes an interlock mechanism, to prevent accidental opening when in the ON position, which can be padlocked for security.
