Compatible Holders & Replacements

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.

  • Voltage rating: 600V AC/DC
  • Current rating: 800A
  • Class: T (fast-acting, high interrupting capacity)
  • Holder requirement: Class T-rated fuse block or fusible disconnect (800A, 600V minimum)

Not sure if this fuse matches your existing holder or disconnect? Send us your equipment model and we'll confirm compatibility.

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.
