Review on Effortless Installation Guide for Smseace Miniature Circuit Breaker by Mike Palma

These were purchased as extra protection and to quickly shut down my solar panels. I have a combine with circuit breakers and a surge arrester, but I need extra security. They were so easy to install, just snap and plug onto the DIN rail. They work flawlessly, have a highly visible green/red window on each switch to show status, and the switch feels good when actuated. I tested them under load and in a surge test they delivered almost 23A. They also tripped at just over 21A after applying the load for over a minute. So they work great for me and don't trip below 20A. These are really good quality DC switches that deserve 5 stars.
