Good quality
Blue Seas electrical items are ones boaters trust. Good quality.

Sturdy feel, correct size, works perfectly
I used these to completely rewire and build a custom panel for my '87 260 Sundancer. Was exactly what I needed and performed perfectly in short-circuit testing! These are a standard marine/rv size breaker that fit in all marine panels, so the other misinformed reviewer complaining about them being small clearly has never seen a marine breaker and probably should have read the description better. They're a little pricey if you have a large panel but they're a trustworthy brand and you should only have to buy them once! I wish they sold their double breakers on Amazon though, I had to buy one of theirs from another website for my main breaker.

Plus 5
Installed a larger water pump on my boat therefore needed to increase the breaker from a 10amp to a 15amp. Perfect fit and corrected my overload problem.

Good replacement unit.
Fit like direct replacement for the original on my cruiser. I trust the name, all that is left is to see what happens over time.

No Mounting Screws
Great little product, although it didn't come with mounting screws. Not even sure what size they're supposed to be. Neither the panel not the breakers have mounting screws. Where do I get them and what is the size and description?

Perfect solution
I needed to combine circuit breaker and a switch in a piece of industrial equipment, this was a perfect solution. I will be using more of these from now on.

Great product for a good price
These 15 amp breakers fit the bill! Used them.to replace the old under rated breakers in my 3500 watt generator. The fit perfectly and came with new screws for everything. Was very happy with the fit and function
