What size fuses are in cars?

Are car fuses standard size?

There are three common blade fuse sizes: the small minis (ATM), mid-sized regular (ATC/ATO) and the large maxis (APX). There is also a low profile version of the mini, the APS, which uses the same universal Amp colour coding system.

What type of fuses does my car take?

Most automobile fuses used in vehicles today are one of three types: mini, standard or maxi. The mini and standard are fast-acting fuses that protect the majority of your vehicle’s circuits, including those for lights and radios.

Are all 15 amp car fuses the same?

All Car Fuses Aren’t the Same

Types differ primarily in size and number of terminals. Physically large fuses are typically used in high-current applications. In the past, vehicles commonly used glass tube and Bosch fuses. They’re found today in old vehicles that are still on the road.

How do I know what size fuse to use?

You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break. When this happens, it stops the electrical power from flowing through the electrical circuit.

What are the big fuses in cars called?

Maxi/APX – These much larger fuses (29.2 × 8.5 × 34.3 mm) can hold more amps than standard or mini fuses. 20 to 120 amp. The classic ATC fuse is a plastic blade type. The amperage is noted by both the color and printed on the top.

Are all car fuses universal?

Not all car fuses are the same, and most cars have multiple fuses of varying sizes for different electrical components. When you are replacing a car fuse, it is essential to replace the blown fuse with a new one of the same type and size. You should also never replace a blown fuse with one of a higher amperage rating.

What are the 3 types of fuses?

Different Types of Fuses – Constriction, Working & Characteristics

  • DC Fuses.
  • AC Fuses.
  • Cartridge Fuses.
  • D – Type Cartridge Fuse.
  • HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
  • High Voltage Fuses.
  • Automotive, Blade Type & Bolted Type Fuses.
  • SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.

What are the different sizes of fuses?

Blade fuses (shown at right) come in six sizes, which are, from smallest to largest: Micro2®, Micro3®, Low Profile MINI®, MINI®, ATO®/ATC® (also called “regular”) and MAXI® or MAX.

What happens if you use a smaller fuse?

Do not use a fuse with a lower rating– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.

What size fuse do I need for a cigarette lighter?

Ever wondered what the appropriate fuse amperage for a cigarette lighter is? Well, it’s recommended that you use an amp fuse with an amperage between 7 and 10, but never anything over 15.

How do you size a car fuse?

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. C Choose FUSE AMPERAGE near the middle of this range.

What fuse do I need for 12V battery?

For a 12V 55W solar charger, you would need approx. 10A fuse.
