The GOUATM30/40 – GOULD 40A Midget Fuse is a reliable and efficient circuit protection solution designed for various electrical applications. With a 40 amp rating, this midget fuse ensures optimal safety and performance in your systems. Ideal for use with circuit breakers and other electrical devices, it guarantees dependable operation every time.
The ATM-series fuse uses the standard 13/32" × 1½" Class CC form factor, so it fits any Class CC-rated midget fuse holder or fused disconnect block — including those from Gould/Ferraz Shawmut, Bussmann, and Littelfuse. Always verify your holder's voltage and ampere interrupting capacity (AIC) rating before installing.
The Gould ATM line has transitioned through Ferraz Shawmut and is now part of the Mersen brand family. Northern Breaker Group specialises in obsolete and hard-to-find electrical components, so whether you need original Gould-branded stock or a verified equivalent, we can help.

Not automatically. The ATM series is fast-acting, while the ATDR series is time-delay. Swapping types can affect nuisance tripping on motor in-rush or, conversely, leave equipment under-protected. Check your equipment's manufacturer specifications for the required fuse type before substituting, and reach out to us if you need clarification.
