Excellent simple explanation on the differences of the 2, a good example how this works in my shop ( machine shop ) I have a 20 amp dedicated breaker in the main fuse panel for a specific lathe, if I take heavy cuts and the amp meter shows high amperage-draw at the top of the amperage rating under full “load “ on the motor plate, in a short time the relay will trip in machine control panel but not at the main fuse panel. Reducing the feed rate while cutting reduces amperage draw in turn reduces “heat buildup in the motor and will prevent the relay from tripping. Some people mess around with the settings on relays but not a good idea if you don’t know anything about the electrical motor rating , as higher than nominal heat within the motor is the killer on the long run 🤒 always enjoy your videos 😎
It needs to be rated higher than the total load you are going to put on it but not a lot higher. Also be CAREFUL, you’re wire has to be sized right out you can cause a lot of damage. There are wire sizing charts everywhere that tell you the size wire needed for any breaker amperage

How do you size the overload relay and Circuit breaker
With great care, lest you burn something down.
