Review: I needed a circuit breaker for a project, the brand name sold me. - I needed a single phase 220v circuit breaker for a project. There are plenty out here on desertcart... but this is electricity in a building that I don't always occupy. I went with a name I recognized, pure and simple.
Review: Mini Breaker for Our Van - Bought this as our main breaker in our van. Looks well built and functions very well, one is for our AC and another for Shore connection breaker. A little pricey compare for others but it’s worth it. Like from another review this is much taller coz of the plastic that divide on top and bottom where the wires go. I see that as added protection yet it did gave me hard time during install, tight fit on the box.

This breaker feels high quality. It is compact, and you should be able to fit many in a small DIN area. I have no quarrels about this breaker--thanks.
