ATC/ATO Blade Fuses (UL) – 5pk

Q: Can I use these for my car?

Yes. These are the standard (regular) ATC/ATO size used in most passenger vehicles and light trucks.

Q: Which size are these?

Standard/Regular ATC-ATO. They are not Mini/ATM and not Maxi fuses.

Q: What is ATO and ATC?

ATO was the original Littelfuse trademark for the standard automotive blade fuse. ATC became the common generic term. In practice both refer to the same standard size — and these fuses are the ATC type.

Q: What does “UL Listed for Canada” mean?

It means the fuses have undergone independent testing by Underwriters Laboratories (UL) and meet Canadian electrical safety requirements. This is a formal UL Listing (not just “tested to”), verifying the ratings and including ongoing production oversight.

Q: How do I choose the right amp rating?

Match the fuse to your circuit’s wiring ampacity and expected load. If replacing a fuse, use the same rating as the original unless otherwise specified by a qualified designer.

Q: Are these good for RVs, boats, and solar?

Yes — they’re commonly used on 12V and 24V DC systems across RV, marine, and off-grid applications for protecting accessory circuits.
