These Bussmann ATM (mini) blade fuses protect 12-volt circuits in your RV's electrical system, from interior lighting to accessory wiring. The smaller ATM footprint fits mini-style fuse blocks and holders commonly used in RVs and tow vehicles.
Each fuse is color-coded yellow to mark its 20-amp rating, with an enclosed element that resists shock and corrosion for a longer service life. They come packaged five to a blister card so you've got spares on hand.
Always replace a blown fuse with the same amperage rating to avoid overloading the circuit it protects.
