FERRAZ SHAWMUT A3T series fuses are fast-acting, Class T fuses that combine high current limitation with a small physical size, making them ideal for applications where space is limited. Their unique dimensions prevent the use of lower-rated fuses, enhancing safety. The glass melamine body provides dimensional stability, while blade-stamped catalog numbers ensure permanent identification. These fuses are commonly used in load centers, 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, demonstrating their adherence to industry safety standards.
