Fuses ATO or ATC?

The operator manual for the WFCO converter specifies ATC "Littelfuse" Type 257 fuses. So far I am only able to find ATO fuses. If it matters, would someone direct me to a seller of the ATC type? Thanks.

    ATC is closed and ATO is open to the environment.  ATC  is considered to be more weather resistant. A general example for their uses, ATC would be used under the hood of a car and ATO (or ATC) in the driver's compartment. You should be able to find ATC fuses at Amazon, Walmart, NAPA, etc.

    I ordered them from digikey.com. Shipping is reasonable.
