FESC100 – GOULD 100A 600V CLASS C FUSE

The GOUFESC100 is a Class C rejection-style fuse, which requires a dedicated Class C fuse holder or fuse block rated for at least 600V and 100A. The rejection feature physically prevents installation into incompatible holders (such as Class H or K), which is an important safety design. Make sure your holder is specifically rated for Class C fuses before installation.

Gould's fuse product lines were acquired over the years by Ferraz Shawmut (now Mersen). If the GOUFESC100 is discontinued or hard to source, equivalent Class C fuses from Mersen, Bussmann, or Littelfuse may serve as direct replacements, provided they match the 100A, 600V Class C rating.

Yes — 100A, 600V Class C fuses like the GOUFESC100 are commonly used in hot tub and spa applications where a fused disconnect is required. Under the Canadian Electrical Code (CEC), hot tub installations typically require a disconnect within sight of the equipment. Always verify that the fuse rating matches your equipment's nameplate specifications and that the holder is rated for the application.
