Topic: Is there such a thing as a 1 amp, DC circuit breaker? (Read 362 times) previous topic - next topic

I've tried googling it but found nothing that meets the requirement. I have an autonomous robot that uses servos. On rare occasion, it gets stuck in some weird position that will cause the servo to burn up. If I had a circuit breaker or even a low amp automotive fuse, I could save myself some money.

The way you have it in your schematic isn't the same as how you have it wired up!

I appreciate the help but that's obviously not it. I did finally find the answer though for anyone else that finds this thread. You use what is called a polyfuse (aka, polyswitch). They are perfect. They are cheap and open the circuit when they get hot while closing the circuit when they cool down. Perfect.

that wasn't your original link


Sure they are, on the left side of the linked page is a listing of various types of fuses. I'd think you would start with a more conventional fuse for testing, but good luck with your polyfuse choise.
