Protection and a switch
While this does give you protection on the line it also works great as a switch to turn off that section of the system in our van. You don't want to use it as often as a light switch but when the van is parked at home I do turn it off. Saves space with two functions in one.

Easy to install, works for what I need it for
Easy to install, easy to break or reset the circuit. Decent terminals for connecting a 10mm² wire

Great Build - Very Satisfied!
Purchased several of these to use for the main feeds coming off of the batteries in my boat and splitting off to the fridge and busbars. The overall build quality is phenomenal, and I love the simple operation/concept. So far, these have held up well in the bilge area, with no noticeable corrosion or degradation. I'll update my review if that changes!

Blue Sea Systems are the best
I have been in the marine industry for 36 years and have had my own boat shop for 30 years and installed many of these and other Blue Sea products in salt water boats, I am here to tell you that Blue Sea Systems components are the best in the industry. Don't be fooled there is a lot imported junk out there, you pay more for Blue Sea but you get the best! I used this circuit breaker under my travel trailer to replace a rusted out factory piece of junk. I am sure that this breaker will last for many years to come.
