These are great. Only downside is the slightly inefficient angle of the line and load BUT you can tweak them if needed, and I needed to. They are very small and take up minimal real estate, however, if you are looking for the ultimate in maximizing battery life: consider others. Klixon breakers are great - dont get me wrong - but you will see a slightly voltage dip using these breakers, as they have a slightly high resistance. If I recall, about 0.3v is expected.

Good quality breaker with a small footprint, solid connection. Have bought a number of these in various amperages. Been flying on my plane for about a year. No problems.
I have installed a lot of Klixon circuit breakers over the years. I have never had a breaker fail. The service on this breaker was fantastic. I can order in the morning & the item will arrive the next day on most items. If it is in the afternoon, then it takes an extra day.
