I use my 50 amp Bussmann breaker for my Minn Kota 101 lb thrust trolling motor. The great part about it to me is that by pushing the red button on the top it opens the circuit. So I don't have to install an on/off switch along with the breaker. When I want to cutoff power to my trolling motor I just push the red button and the circuit opens, shutting off power to the motor. To turn it back on/close the circuit, you just have to slide the little black arm back into it's "on" position and you're back in action.
Plus it's a great safety feature.

This product seems quality made, and is waterproof. The circuit switch works very well & appears heavy duty. I like the fact that it is compact and can be installed close to the battery as recommended. I would definately recommend this product.

I used this for the first time this last weekend and it worked as it says it should. I have it mounted on the top of the battery box on my pontoon boat. After connecting it to the battery via separate battery cables (don't forget you will need them), I connected it to my electric motor an now have no worries about it. Not only does it take the place of a fuse, and it is so much easier than replacing fuses, I also use it as the on and off switch for the motor. Bravo.

I got this for use on my trolling motor (boat/fishing) so that the motor won't burn up if I jam the prop on a log and stop the motor.

As I was hooking it up, I accidentally shorted across the circuit breaker (after I hooked it up to test it, I dropped the circuit breaker and it happened to land perfectly on the negative terminal of the battery). After the momentary flash of sparks, the breaker tripped as it should. Very easy to reset, just squeeze the lever back to position.

This is a GREAT thing to have on the boat.

Very nice breaker. Nice and small and seems built very well. Solved some issues I was having with a standard ATO inline fuse that was overheating due to internal short and this is just a much better solution. I wish the rubber line holding the caps was a bit thicker as I broke it off but was my own fault.

I'm very pleased with my Amazon purchase of this high quality Bussmann product. I mounted it at the back of the boat just after my trolling motor batteries. When not in use I push the red button to open the circuit while charging the batteries. I recommend this product for anyone wiring their new trolling motor.

Bought it for my RV air ride pump. It runs more then it should and I was always replacing fuses. Replaced it with this reset breaker now I am not replaces anything merely resetting one makes it a lot more convenient.

I have used these circuit breakers before on some of my higher amperage items (75 amps and 100 amps) and was looking forward to being able to use the 50 amp version of this circuit breaker. On this application, I used the 50 amp circuit breaker in place of a HEAVY DUTY fuse in my RV on a circuit that was giving me trouble. As I ran down the "short", the circuit breaker tripped as it should have and it didn't cost me $5.00 each time like the heavy duty fuses. Once I ran down the issue with the circuit (frayed wire, of course), I left the circuit breaker in place. These are my "go to" replacements when fuses and fusible links go out and I will continue to use them on my RV, boat, etc.
