I am i need of a 12 Volt DC Circuit breaker ( 30-40 amps) that is an inline breaker that trips in a pull type application by weight 300-400 pounds. I have used some in the past that are flat hinged type but need one that is cylindrical about 2" in dia and 3-4" long. Have seen them in use years ago but do not remember the manufacture.
Is this actually a circuit breaker that trips according to an applied weight, rather than an electrical overcurrent? Or is it a specialized switch? I googled but didn't find or learn anything.
Yes it trips by weight the hinged ones we used were built in house at our plant, I have seen years ago an inline model but do not know the manufacture.
If i don't find one that works i will build what i need.
Wow, never heard of anything like that. What is the purpose for using weight instead of amperage? There is a place near me that sells odds and end breakers but I have no idea if they would have something like that. www.tampabaybreaker.com/
I need one for a 12 volt winch project i am doing, Needs to break the circuit at 350 pounds, I have made hinge type ones in the past but have seen some that are round , about 4" long.
Oh ok makes sense now. I will give the breaker place near me a call for you tomorrow and see if they know what I am talking about. If they do then I will say great and let you know, lol.Quote:

When you made your own, how did you design them to open at 350#?Quote:

These companies make a bunch of load limiters in various configurations.

Yes it does, I think i will just make one, i have not seen the round style ones for several years. They could have been some type of older military breaker. The ones i have made years ago i used a spring type starter switch from an older car and a spring to make it adjustable on weight, more of a hinge type breaker .
So it is really just a load switch, not a circuit breaker type device.
That last link is the closet thing to what i have made, I will be working on building one and post pics as soon as i get my daughters new kitchen out of my shop, they have been coming out on there days off building cabinets. We are down to spraying the last 2 coats of finish and have to build the Corian Countertops next.
