Power fuse tubes are the insulating, arc-quenching housings at the heart of medium- and high-voltage expulsion and current-limiting fuses. Unlike the small plug fuses found in household panels, the tubes we discuss here are engineered composite components that contain the arc, withstand thousands of amps of fault current, and keep […]

Fuse tube production splits into three voltage classes: high-voltage, medium-voltage, and low-voltage fuse tubes. All of them must have arc-extinguishing characteristics. This article walks through how a vulcanized fiber fuse tube and a melamine tube are made, so you understand what you are buying. The Three Voltage Classes and What […]
