Class L Fuses
Marshall E. Campbell Co has a wide range of Class L fuses filtered by amperage, diameters, and interrupting ratings to help you buy the right fuse for the job. Call us to learn about Bussman series Low-Peak Upgrade program! We have the fuse inventory needed for your next electrical installation project. Class L time-delay fuses are suitable for high-current power applications. They can withstand current overload for a short time and will not open when exposed to harmless temporary surges, such as when starting a motor. Timedelay – 4 seconds (minimum) at 500% of rated current. Industry’s only UL Listed and CSA.
