The A6T45 – GOULD 45A 600V Class T Fast Acting Fuse is engineered for superior short-circuit protection in high-demand electrical systems. Its fast-acting design ensures quick response to overloads, safeguarding your equipment and preventing damage. Reliable performance makes it ideal for industrial and commercial applications requiring robust protection.
The A6T45 is a Class T fuse, which requires a Class T-rated fuse holder or fusible disconnect sized for 600V and 45A. Class T fuses have a distinct compact blade profile that is not interchangeable with Class J, R, or other common fuse classes, so ensure your holder is specifically rated for Class T. Contact us if you need help sourcing a compatible holder.
Yes — Class T fuses are standardized by dimension and performance class, so the Gould A6T45 is generally interchangeable with other 45A 600V Class T fast-acting fuses such as the Ferraz Shawmut/Mersen A6T45 and the Bussmann JJN-45. Always confirm the replacement matches on voltage (600V), amperage (45A), speed (fast-acting), and interrupting rating (200kA) before substituting.
