glass fuse size

Common glass-fuse sizes include tube fuses such as 5 × 20 mm and 3.6 × 10 mm, and automotive AGC glass fuses that are about 1/4 inch in diameter by 1-1/4 inches long.

Listings typically show metric sizes (for example, 5 × 20 mm or 3.6 × 10 mm) and imperial sizes (for example, 1/4 inch × 1-1/4 inch for AGC automotive fuses).

Common ratings include 1A, 2A, 2.5A, 3A, 4A, 5A, 6A, 7.5A, 8A, and 10A for tube-style fuses, with higher automotive ratings (for example, 20A) shown for some AGC types.

The listings show 125 V for several tube-style glass fuses, and a 250 V rating is mentioned for one automotive-style fuse in the results.

The listings specify glass construction—described as durable or high-quality glass—so the fuse element is visible for inspection while providing circuit protection.

AGC automotive glass fuses are described as roughly 1/4 inch in diameter and about 1-1/4 inches long.

Dimensions are reported as diameter × length in millimeters (e.g., 5 × 20 mm) or in inches (e.g., 1/4 × 1-1/4 in). Some listings also include overall package dimensions.
