Blue Sea Systems 285-Series Surface-Mount Circuit Breaker, 40A

Easy to install, easy to break or reset the circuit. Decent terminals for connecting a 10mm² wire

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.

Great device for controlling my air horn/locker compressor in my truck. Much better solution than crappy fuse housings. Would like the terminals to be covered a little better but might be able to do that on my own with some boots.

Very high quality and reputation. I only trust Blue Sea for DC electrical components.

En las baterías

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.

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!

Provides reliable protection for my DC to DC converter.

Expensive, but not when compared to the quality, reputation and reassurance of Bluesea products

Blue sea quality. Second to none.

Does not trip on even double amperes than rating.
