What is an ANL type fuse?

What is an ANL type fuse?

ANL type fuses are the most common types of fuses used to protect the main power wire in car audio systems. ANL fuses are available from Bussmann in sizes from 35 amps to 750 amps. The following photo shows a 200 amp ANL type fuse. In this fuse holder, there is no wire-terminal block.

What sizes do ANL fuses come in?

ANL fuses come in sizes from 35 – 750 amps. They are typically less expensive than Re-settable Breakers.

How do ANL fuses work?

Basically inside a fuse, there is a thin metal strip and depending on the fuse rating it will be thinner or thicker. If there is excessive current the fuse will blow the metal strip and interrupt the electrical circuit in order to prevent overheating or catching on fire.

What is the difference between AMG and ANL fuses?

ANL fuses have a higher AIC rating – 6000 amps. AMG fuses only have a 2000 amp AIC rating. That is the largest difference. It relates to battery bank size and the unique ability of a fuse with a low AIC rating to keep the circuit closed after blowing – in effect welding shut.

What is the difference between a mega fuse and a ANL fuse?

MEGA fuses are suitable for 12V and 24V battery systems and are mainly intended for short circuit protection since these are relatively slow acting fuses. Main applications are protection of batteries, alternators and cabling. The ANL fuses that we have in stock are suitable for 12V, 24V and 48V battery systems.

Are ANL fuses directional?

No. Fuse is a conductor in normal circuit. So it’s without any direction or polarity and orentation.

Are ANL fuses waterproof?

Product Description. The FH-20 is a high current handling inline waterproof fuse holder that accepts one 0, 2, or 4 gauge in/output and is rated to handle up to 300 amps of current.

How do you calculate what size fuse you need?

B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A.

Where does the fuse go in a 12v circuit?

Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows. (Of course, if the positive terminal is considered Ground, place the fuse near the negative terminal.)
