150 AMP Fuse Holders,Audio Circuit Breaker,Reset Fuse Inverter, 12V-48V DC Fuse Holder,Replace Fuses,with reset button,for Automotive Marine Boat Audio System Current Overload Protection

I did have some questions as I was using this on my battery bank , as when I plugged in a charger, this fuse trippedI initially suspected that the fuse was faulty , as I could not see any issue in my systemTurns out , there was a bad connection in one of my batteries that was causing a big current draw from the battery this was attached to ...so have to give this a 5 star.. saved me a battery

Good quality

I'm using this as a negative battery disconnect to avoid a dead mower battery from parasitic draw and I haven’t had a dead battery since. Just had to use a 8" battery cable to run the breaker in-line on the negative side. Works like a charm

Very cheap plastic. I dropped it and busted the whole corner off. Also dont think it trips at 300 amps. more like 100amps. After 2 weeks of using it. It quit working altogether. Do not buy this.

Looks good hopefully it'll keep my car safe from short circuits !!

I used this on my boat to protect my trolling motor, it works great. I highly recommend this product.

No complaints work good

I liked the idea that this product would replace ANL fuse for car stereo, in the event that it possibly tripped the breaker for some odd reason. But on the second week it froze in place and will not allow you to trip and reset to check for safety purposes. I will be removing this ASAP as this is clearly a fire hazard. I've had success with other brands of this type of resettable fuses, this was not one of them.
