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.
Ato fuse vs mini fuse.
The ato fuse is open on the bottom exposing the fuse element between the blades.
For newer vehicles these fuses protect the additional circuits and onboard electronics without adding bulk.
This allows you to use more fuses in the same amount of space.
Regular apr atc ato ats blade type fuses also known as standard were developed in 1976 as ato by littelfuse for low voltage use in motor vehicles.
There are three common blade fuse sizes.
Bussmann makes the atc that also complies with the same iso 8820 3 and sae j1284 standards.
Mini apm atm.
This allows you to use more fuses in the same amount of space.
It generally cannot be used in a fuse block that is made for an atc fuse as it will not fit in properly.
Mini fuses look like ato and atc fuses but are much smaller in size.
The only difference is it is smaller than an atc fuse in actual size.
I have a couple of maxi blade fuses and holders kicking around and am wondering if i can use them to fuse each of my 2 car stereo amps.
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 mini fuses were developed in the 1990s.
An atm fuse is considered to be a mini fuse and it came out in the early 1990s.
