Littelfuse ATO Blade Fuse

The Littelfuse ATO blade fuse is a standard-size automotive blade fuse (also called an ATO fuse or ATC-style blade fuse) that protects vehicle electrical circuits from overcurrent damage. Littelfuse is a long-established maker of circuit protection products, and the ATO line is widely used in cars, trucks, motorcycles, boats, RVs and other low-voltage DC systems.

Key Features:

• Plastic blade housing with a fusible element that opens the circuit when current exceeds the fuse's rating
• Standard ATO blade form factor that fits common blade-style fuse blocks and panels
• Color-coded housing for quick amperage identification
• Clear housing lets you see the element and check whether the fuse has blown
• Easy to install and replace, with no tools needed in most fuse panels
• Suited to replacing blown fuses and to adding protection to accessory circuits

Keeping spare ATO blade fuses on hand helps you restore a protected circuit quickly. Always replace a blown fuse with one of the same amperage rating specified for the circuit.
