What is a 3AG fuse?
The 3AG cartridge, fuses are miniature glass electronic fuses. The 3AG designation stands for automotive glass and reflects its original design as an automotive fuse back in the 1930’s. The 3AG fuse size is constructed with a glass body and is less expensive than the 3AB, ceramic fuse.
Is 3AG the same as AGC?
What’s the difference between AGC and AFE? 3AG is a 1/4″ x 1-1/4″ fuse. AGC is a fast blow fuse. Lower ratings are spec’ed for 250 volts higher at 32.
What are the sizes of fuses?
Size groups
| Blade size | Blade group | Common ratings (maximum current) |
|---|---|---|
| Micro2 | APT, ATR | 5, 7.5, 10, 15, 20, 25, 30 |
| Micro3 | ATL | 5, 7.5, 10, 15 |
| LP-Mini (low profile) | APS, ATT | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
| Mini | APM, ATM | 2, 3, 4, 5, 7.5, 10, 15, 20, 25, 30 |
What is Type C fuse?
Class C fuses are not dimensionally or electrically interchangeable with other North American fuses. They feature ceramic bodies and bolt-in mounting. They are for short-circuit protection only, in motor controllers, for example, where overload protection is provided by an overload relay.
What are the big fuses called?
MIDGET
The largest size fuse shown in the chart is the 5AG, or “MIDGET,” a name adopted from its use by the electrical industry and the National Electrical Code range which normally recognizes fuses of 9/16” x 2” as the smallest standard fuse in use.
What is the difference between AGC and MDL fuses?
The AGC fuse type is a fast-acting glass tube fuse. Upon circuit overload, the fuse will almost immediately sever the power connection, protecting valuable electronics. MDL has a slow interrupt speed, allowing for minor and short jumps in amps without causing the fuse to break.
How do you know what size fuse to use?
The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse.
