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.
