Maxi fuses are
larger than ATO/ATC fuses and offer protection for high amperage vehicle circuits
. They are a blade-type fuse designed to replace fusible links or fusible wire. The fuse link is completely enclosed to help protect against moisture and other corrosive or damaging elements.
What is the difference between mini and maxi fuses?
Blade fuses provide protection for amperage ratings up to
80A
. Bolt down fuses (shown at left) provide protection from 30A to 600A and are ideal for battery and alternator circuit protection. … For example, a clear-colored MINI fuse signifies 25A, while clear in a MAXI fuse signifies 80A.
How big is a maxi fuse?
MAXI® blade fuses are available in
20-60 amps
and each amperage fuse carries standard color coordination.
What is the difference between ATC and ATO fuses?
ATC and ATO are virtually the same fuse
. The C in ATC stands for closed which means the element is closed within the plastic housing. The O in ATO means the element is open to the atmosphere and subject to environment.
What are the different car fuses?
There are 4 main types of fuses:
Micro, Mini (APM, ATM), Standard (APR, ATC, ATO), and Maxi (APX)
. Each fuse can be color coded with the appropriate amperage rating on top.
What are the 3 types of fuses?
- 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 does ATM fuse stand for?
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 are Maxi fuses used for?
Maxi fuses are larger than ATO/ATC fuses and offer
protection for high amperage vehicle circuits
. They are a blade-type fuse designed to replace fusible links or fusible wire. The fuse link is completely enclosed to help protect against moisture and other corrosive or damaging elements.
What happens if you use a lower amp 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.
Do fuses go bad with age?
Unused fuses can expire due to aging
. It's also possible that you have an intermittent problem with the switch or the starting capacitor. Try to replace the fuse first to determine if it's an aging issue.
What are ATC fuses used for?
The BussmannTM series ATC fuses are a range of UL® Recognized fast-acting blade fuses
for automotive and low-voltage control circuits
. All catalog numbers for these fuses feature the same form, fit and electrical performance characteristics regardless of their housing materials. identification of amp rating.
Are all vehicle fuses the same?
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.
How do I know what fuse to buy?
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.
What type of fuse do I need?
Fuse panels typically provide
30 or 60 amps of
power, and the bare minimum for a home with modern appliances is now considered to be at least 100 amps, with 150 or 200 amps preferable.
