Overview

The Mersen Amp-Trap AG fuse series, including the AG3 (SKU: AG3), offers reliable branch-circuit protection for lighting, heating, and appliance circuits. This Class G fuse operates at 600VAC and has a 3A rating with time-delay characteristics, ideal for applications requiring protection against sustained overloads without nuisance tripping. Manufactured by Mersen in France, the AG series is UL Listed to standard 248-5 (File E2137) and CSA certified to standard C22.2 No. 248.5. Key features include a fiberglass body for dimensional stability in harsh industrial settings and current-limiting capabilities with a 100kA I.R. AC rating. The unique physical size of Class G fuses prevents interchangeability with other fuse classes, ensuring correct application. The AG3 fuse is a direct replacement for Bussmann SC and Littelfuse SLC fuses. Its dimensions are consistent with other AG1-15A fuses, measuring 1.3 inches (33.3mm) in length and 0.40 inches (10.3mm) in diameter. This fuse is suitable for general industrial applications where robust and specific protection is paramount.
