The GOUA6T800 is a Gould 800A, 600V Class T fast-acting fuse, built to ANSI Class T dimensions. Class T fuses require a dedicated Class T fuse holder or fusible disconnect rated for the Class T form factor — standard Class J, R, or L holders are not compatible. Suitable holders are available from major manufacturers (Mersen/Ferraz Shawmur, Eaton/Bussmann, and others) rated to 800A, 600V AC/DC. Cross-reference replacements include equivalent Class T fuses from Mersen (A6T800) and Eaton/Bussmann (JJN-800 / JJS-800 series) where Class T ratings align.

Gould Class T fuses carry a high interrupting rating of 200,000A RMS symmetrical at 600V AC, making them suitable for use on systems with very high available fault currents — a key reason they're specified in industrial and commercial applications.
No — Class T fuses have a unique physical dimension that is not interchangeable with Class J, Class L, or other ANSI fuse classes. You must use a Class T replacement (800A, 600V) in a Class T-rated holder. This rejection feature is intentional to prevent the installation of a lower-interrupting-rated fuse.
Gould's fuse line has transitioned through several brand evolutions (now largely under Mersen/Ferraz Shawmur). The GOUA6T800 may be available as new-old stock or through equivalent cross-reference.
