5.0 out of 5 stars How these reset and work
(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } I love these things. They worked a s expected in my situation. I normally oversize them a bit along with the wire. This self-resetting fuse is a type of fuse that can automatically reset itself after an overload or short circuit condition has been cleared. Here's a basic overview of how it works so you will know when it applies to your specific needs:1. Normal Operation: Under normal operating conditions, the self-resetting fuse behaves like a regular fuse, allowing current to flow through it without resistance. These are usually made from a special conductive polymer material or a metal alloy that has a low to no resistance when not under a stress condition. This allows current to flow as you would expect.2. Overload Condition: When there is an overcurrent or short circuit, the fuse experiences a significant increase in current flow. The heat generated by the excess current causes the polymer or metal alloy inside the fuse to heat up. This acts ALMOST like a slo-blow when the current is over rating just by a bit. It may take a few minutes to heat up before it "blows". This will protect the wire for the most part. This "slightly" over condition can cause strange behavior because you can blow the fuse, a few minutes later it cools down, starts to work again, and then blows again. Those are marginal cases however. When sized right they are reliable.3. Current Limiting: As the material heats up, it changes its resistance. In a polymer-based or metal alloy self-resetting fuse, the material's resistance increases sharply when it reaches a certain temperature. This is known as "The Curve" in these fuses. This high resistance effectively reduces the current flowing through the fuse to a very low level, thereby protecting the circuit.4. Cooling and Resetting: After the overload condition is removed (and your wires aren't burned up!) and the current returns to normal levels, the fuse cools down. As it cools, the resistance of the material decreases, allowing current to flow through the fuse again. This process resets the fuse to its normal operating state.5. Reusability: Unlike run of the mill traditional fuses, which need to be replaced once they blow, self-resetting fuses can be used repeatedly. They automatically reset themselves after the overload condition is resolved.I use these fuses for things that are super critical to me like the electric brakes on my trailer. If there is a one time overload for some reason or a short that is on again and off again as the trailer moves, what I can hope is that the fuse resets and the brakes are there when I need them. A normal fuse would blow and never automatically reset leaving me in a situation where I might be without brakes. This isn't foolproof of course, as a bad enough issue and the fuse will just stay "blown" but it is a margin safer than a standard fuse or a breaker.I hope you found this useful!
5.0 out of 5 stars works great to clean up wiring under the hood.
great price and fast shipping
5.0 out of 5 stars very satisfied
work great
4.0 out of 5 stars Works
Got these for camper due to the other ones rusted, easy to install and identical to the old ones, good on price.
5.0 out of 5 stars Perfect replacement!
Just what I needed. 4 of these 30 amp for the price of 1. Perfect fit for my travel trailer replacement. Have spares now also. Btw, if you need 50 amp also, like I did, just get em here at the same time as you get these, as all stores I went to did not have the 50s.
5.0 out of 5 stars 20 amp circuit breaker
These circuit breakers were perfect for the application I needed them for. Fit perfectly and I like the rubber cap to protect them from accidental arcing when touched by accident
5.0 out of 5 stars Great product
Plastic covers are a pain. Threw them away. Great product at a great price. Will buy again.
5.0 out of 5 stars Bargain bulk price for 4 count – but plastic case is trickery to securely mount
These are very good automatic reset 12 volt circuit breakers. I use them for the Power supply wire for Trailer Brake Controllers. If something shorts, and the breaker trips, you may just get the power back on for an emergency stop. The only problem with these plastic case automatic reset 12 volt circuit breakers is that the case is made of delicate plastic. The plastic is good for insulation, but not so good for getting a secure mount. With the metal case type, with metal mounting tabs, you can bend the metal tab to orient the case in a different position. With the plastic case you are limited to flat mounting with the whole automatic reset 12 volt circuit breaker sticking out of the mounting plate.
Works good
