The A6T100 – GOULD 100A 600V Class T Fast Acting Fuse is designed for superior performance in industrial applications. This high-quality fuse provides reliable protection against overcurrent, ensuring the safety and longevity of your electrical systems. Its fast-acting design allows for quick response to overloads, making it an essential component for your equipment.
No. Although both Class T and Class J fuses share a high interrupting rating (200kA), they have different physical dimensions and rejection features. Class T fuses are more compact and use a distinct blade/ferrule profile specifically to prevent cross-installation. The A6T100 requires a dedicated Class T fuse holder rated for 600V — installing it in a Class J holder is not permitted and would be a code violation.
The Gould A6T series has transitioned through Ferraz Shawmut and is now part of the Mersen product family. The A6T100 remains an active part number and is also directly cross-referenced to the Bussmann JJS-100. Northern Breaker Group specializes in both current-production and hard-to-find fuses — contact us or visit one of our Calgary, Edmonton, or Vancouver counters for availability.
Yes. Class T fuses are recognized for both AC and DC applications; however, the DC voltage rating is typically lower than the 600V AC rating — commonly 300V DC for this class. Always verify the specific DC voltage rating on the fuse label or datasheet before use in a DC circuit, and ensure your application and holder are rated accordingly. Contact us if you need clarification for your specific installation.
