What are the different types of blade fuses?

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. The regular-sized ATC fuse is more common than the ATO.

What size are mini blade fuses?

Mini Blade fuses are 10.9mm wide, 16.4mm tall and 3.8mm thick. Low profile Mini Blade fuses are the same width and thickness, but only 8.73mm tall making them 7.5mm shorter in height to save space. Both of these fuse types are available in current ratings from 2 to 30 amperes.

Are all blade fuses the same?

The primary difference between the various types of blade fuse is the size, and as a general rule, larger fuses are typically used for higher current applications. As a result, you must ensure the fuse you select has the right current rating for the equipment.

Are blade fuses Colour code?

Keep in mind that there are several different types of blade fuses beyond the standard ATC size too, including Micro, Mini, and Maxi styles….Fuse Color Codes, by Amp.

Color Rating
Green 30
Aqua Blue 35
Orange 40

What size blade fuse do I need?

Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse. Cross Reference that fuse size to verify that it’s below the Maximum fuse size called out by this chart.

What color is a 30 amp blade fuse?

Light-Green
The 30 amp CB is color coded Light-Green.

What is difference between ATO and ATC fuses?

The ATC has a fuse element that is closed (hence the “C” in the code) inside the plastic housing, sealing it from the environment to prevent corrosion from developing. The ATO fuse is open on the bottom, exposing the fuse element between the blades.

What is a mini fuse?

Mini fuses look like ATO and ATC fuses but are much smaller in size. This allows you to use more fuses in the same amount of space. For newer vehicles, these fuses protect the additional circuits and onboard electronics without adding bulk. Mini Fuse Facts: Available in amperage ratings of 2A to 30A.

How do I know what kind of fuse I 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.

What are 35 amp fuses used for?

Bussman’s MAXI (MAX) Automotive Blade Fuses with 35 Amp Rating (Yellow) are designed to protect circuits in the wiring harness – usually found under the hood, in a fuse panel, or supplementary panel near the battery and are ideal for use with aftermarket accessories.
