Great product

I've used a number of these without any trouble. They lock on a normal DIN rail, and are easy to remove if necessary. Wire clamps are fine. Make sure these are suitable for your application. They lack the certifications required for some purposes in the US.

Good breaker no complaints

Using in a solar project system. These are for AC. Make sure if you are using these in the 120 volt ac portion of the project. For the DC side the breakers needed are marked for DC. Some DC breakers show polarity. Check to see that the DC solar voltage input is connected to the "+" terminal. on mine, this was on the bottom.

I bought this and a 10A breaker that I use to troubleshoot blown fuse components.

Works as expected
