The FERRAZ SHAWMUT A3T and A6T series are fast-acting Class T fuses that combine high current limitation with a small physical size, preventing substitution with lower-rated fuses. These fuses are ideal for applications requiring both high performance and space efficiency. Their glass melamine bodies provide dimensional stability, and the blade-stamped catalog numbers ensure permanent identification. They are commonly used in load centers, panelboards, switchboards, circuit breakers, and metering centers.
