A6T150 – GOULD 150A 600V CLASS T FAST ACTING FUSE

The A6T150 is a Class T fuse and requires a dedicated Class T fuse holder or fusible block rated for at least 150A and 600V. Class T fuses have a unique form factor that is not interchangeable with Class J, Class R, or Class CC holders. Always verify your holder's ampere and voltage rating before installation.

Yes. The A6T150's fast-acting characteristic and high 200kA interrupting rating make it well suited for protecting motor branch circuits, industrial equipment, and other high-fault-current applications up to 600V. For motor feeder applications, confirm that the fuse's fast-acting curve aligns with your motor's inrush tolerance — a time-delay fuse may be more appropriate for some motor loads.

Direct equivalents to the Gould A6T150 include the Mersen (Ferraz Shawmut) A6T150 and the Littelfuse JLLS150, all sharing the Class T form factor with 150A, 600V, and 200kA ratings.
