Buy Young Marine Circuit Breaker for Boat Trolling with Manual Reset,Water Proof,12V- 48V DC (Surface Mount-30A): Battery Switches - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Makes me much more confident connecting things to my cart - This made it much easier to connect the step down converter to my 48 V lithium golf cart battery. I had a transformer connected and it failed, but every time that I had to disconnect and reconnect it, there would be a big spark (which the instructions said was normal). With this, I can break the circuit so there isn't a spark (makes me nervous). Also, if I am going to be no using the cart for a while, I can break the circuit to stop the small amount of vampire draw from the step down converter. Review: Durable - Does what it needs to do. Used it for years now. Left the battery on it without disconnecting and still fine. Absolutely recommend grabbing these for on the water!

Easy to install
Easy to install and switch off the power. I have not seen the device trip - that’s a good thing for me. Compact and easy to turn on/off

Good breaker for shuttle bus conversion
I purchased this breaker for my shuttle bus conversion to run in between my battery bank and the battery charge section of my Progressive Dynamics converter. The breaker is of good quality, is easy to install, and easy to operate (resetting after tripping, etc.). One of the nice features of this breaker in my situation is the ability to manually “trip” the breaker when my rig will be sitting for a while to prevent (or slow, at least) battery drain.

Battery cut off
Used this to replace the fuse located on the tongue of my Rockwood 2109S travel trailer. Like that I get shut off or reset power from the battery bank.

Chinese
Made in China. I searched 'Young Marine' to see if I could tell where they were made. They claim to have their own manufacturing facility but didn't say where. I should have known. I haven't installed this and probably won't. It looks ok, but fine looking Chinese breakers I've used usually fail within a year.

Don’t use it anymore.
I added a parallel feed positive to a larger inverter on my rv. Put this between battery and inverter. Problem is it trips if there’s a load on the system when the transfer switch activates

Just what I wanted.
High quality part, shipped on time and arrived on time. What more could you ask for?
