UL Class Fuses
UL Class fuses meet size specifications and electrical ratings established as industry standards to ensure that fuses with the same ratings can be interchanged and will perform as expected regardless of brand. These electrical-protection devices prevent damage to equipment by opening a circuit when current flow exceeds the fuse's current rating. Their interrupting rating (breaking capacity) specifies the highest current the fuse can interrupt at rated voltage without failing or rupturing.
