FERRAZ SHAWMUT A6T30 fuses are fast-acting Class T fuses engineered to provide high current limitation within a small physical footprint. Their unique dimensions prevent the use of lower-rated fuses, enhancing safety and reliability. Constructed with a glass melamine body, these fuses offer superior dimensional stability, while blade-stamped catalog numbers ensure permanent identification. Common applications include loadcenters, panelboards, switchboards, circuit breakers, and metering centers. They are UL listed to standard 248-15 and CSA certified to standard C22.2 no. 248.15.
