Miniature Circuit Breaker 120V/240V ac Circuit Breaker 1 Pole 20Amp Smart Circuit Breaker DIN Rail Mount for Marine Power Systems,Solar photovoltaic Systems(C20A)

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.

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

Good breaker no complaints

Exelente , todo bien gracias

Justo lo que necesitaba

Although this breaker worked fine initially, after about a year in service (used to cut power to circuits under construction) it began randomly tripping. I checked the actual current draw, and it was tripping at 1/2 Amp.The issue seems to be the holding friction for the on position has degraded from usage.At least these DIN rail breakers are easily replaced.
