How To Determine the High Voltage Fuse You Need

The fastest way to determine an existing High Voltage Fuse is through the fuse Catalog Number found on the nameplate.

If nameplate data is faded or unavailable (older nameplates are notorious for having time worn nameplate data), the Manufacturer’s Name, Type (Ex. SM5, CLE, SMU), Voltage Rating and Ampere Rating of the existing High Voltage Fuse would be key factors in determining a suitable High Voltage Fuse replacement.
