Review on 📚 Essential Guide: Smseace Miniature Circuit Breaker Installation for Industrial Electrical Systems by Brian Whitmore

These were purchased as additional protection and quick disconnect for my solar panels. I have a combine with a circuit breaker and 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.
