6mm x 30mm AGC/3AG Fuse

6mm x 30mm (0.25-inch x 1.25-inch)

The 3AG cartridge fuse is one of the most popular fuses available. The 3AG fuse dimensions are 1 1/4-inch long by 1/4-inch (30mm x 6mm) in diameter. The 3AG designation stands for automotive applications and reflects its original design as an automotive fuse in the 1930's.

Fuses are an essential part of many system designs, and we’ve come to depend on them since the earliest days of electricity. The basic concept of using a fusible link—which self-heats due to current flow and then opens to cut off current flow if there is an overcurrent condition: it is simple, reliable, clear cut, and unambiguous.
