I needed a single phase 220v circuit breaker for a project. There are plenty out here on Amazon... but this is electricity in a building that I don't always occupy. I went with a name I recognized, pure and simple.

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.

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.
