AGC vs ATC fuse
Not interchangeable. AGC is a glass tube fuse (6.35 × 31.75 mm) used in electronics and panel holders. ATC is a blade fuse used in automotive fuse boxes. They require completely different holders.
Side-by-side comparison
| Property | AGC (glass tube) | ATC (blade) |
|---|---|---|
| Form factor | Cylindrical glass tube | Flat blade with plastic body |
| Dimensions | 6.35 × 31.75 mm | 19.1 mm tall, 18 mm wide |
| Holder type | Fuse clips or panel-mount holder | Blade fuse socket in fuse box |
| Voltage max | 250 V AC | 32 V DC |
| Current range | 1/16 A – 30 A | 1 A – 40 A |
| Common use | Electronics, appliances | Automotive fuse boxes |
| Blown indicator | Broken wire visible in glass | Broken bridge visible in plastic |
Verdict
These are entirely different physical fuse types. The only shared attribute is the amperage rating system. You cannot use an AGC in a blade fuse socket, and you cannot use a blade fuse in a glass tube fuse clip or panel holder. Identify your holder type first, then match the amperage.
Which do you need?
- AGC — if your device has a cylindrical fuse holder (common in audio equipment, test instruments, and older appliances).
- ATC — if your fuse is in a vehicle fuse box and has two flat metal blade terminals protruding from a plastic body.
