100A Auto Car Inline DC Circuit Breaker Reset Switch Inverter Protection

I installed this 150A circuit breaker in my car audio system and it has worked perfectly. The product quality is very good, with durable materials and a compact design that makes installation easy. I especially like the transparent covers on both ends, which add extra protection against short circuits. The manual reset button is very convenient. Instead of replacing a fuse every time there’s an overload, I can simply reset the breaker and keep going. The switch feels solid and well-made. ✅ Pros: • Easy to install • Transparent protection for terminals • Functional and safe reset button • Supports up to 150 amps, great for high-power setups ❌ Cons: • Size might be a bit large for very tight spaces Overall, this is an excellent option if you’re looking to protect your audio system or any 12V/24V electrical application. Highly recommended.

I have 6 gauge wire and it was a perfect fit for my power cable running from my battery to my 1200 watt amplifier in my car. It came early and I would use for any future wiring that calls for a breaker to be added. Great value solid construction. I'm impressed will buy again for future projects. Update: 8 months later and this breaker is performing at 100%. My breaker is located in the engine compartment close to my battery and i have had no issues with heat or false tripping. A game changer still and a hassle free purchase. Thank you for the great product

This works perfectly as a fuse for my car subwoofer amp as well as a quick killswitch. Have a hatchback, and when I want to take my subwoofers out and need the space, I can flip this switch to safely cut all power to the hidden amplifier. Fit the 2 AWG size power cable with no issues. The plastic sleeve is perfect to protect the wire.

I will say, this product works and its doing an excellent job for what I need - HOWEVER there are two glaring issues. 1. The "reset" button is INSANELY sensitive. If you so much as press carpet up against it (as in installing under carpet) it will be enough to press the button or cause a twitchy connection. I had to build a sheet metal cover for my switch because the carpet laying on top of it was enough to trip the button if the carpet shifted at all. 2. The grommets do not fit 4awg wire. You'd think if you're going to advertise this as fitting 4 gauge wire, the "water tight" grommet should be able to fit 4 gauge wire, so I just had to use the open ended plastic caps which is no biggie to me. Id be more upset if this breaker was exposed as then it would not look as finished as I would like. All things considered if you're placing this in a very safe place that has NO way of even being grazed near the button, and you're okay with the rubber grommets not fitting larger wires - its a good product for money.

Great Price , Fast Shipping, No need to worry about having a spare fuse, if you tend to overwork your amp., just reset and rock on....Best part for me is if my ride has to be in the shop, I can just push the button and amp power is not available for when I do NOT want mechanics or inspectors playing my tunes. Be sure to get the correct amp rating for your rig.

So far works like it should. Installed on my boat. Using the inserts for 8ga wire, install was straight forward and simple. Easier than crimping in an in-line fuel. Insert one wire and tighten then inert other wire and tighten.

If you need a circuit breaker, and you don't have a lot of money to spend, this will work. The circuit breaker itself seems to be sealed pretty well. The area where the wires go into, That's not too sealed. But that's kind of normal when it comes to these circuit breakers. About the max size wire you can fit in there is four gauge. And if you're using a hundred amp circuit breaker you don't want to use anything smaller than 4 gauge. If you're installing an aftermarket amplifier you want to make sure this is between your battery and your firewall under the hood. I went with a circuit breaker because I didn't want to have to deal with fuses. If the circuit breaker pops, you can just reset it. It's not the best built circuit breaker, but it does work just fine.
