Correct^^^^^
Small button on end is the RESET button for that CB
AUTO Reset.....resets automatically ---no need to power down/power up, no disconnecting anything thing

Fuse goes in series with the load, to protect the power supply if the load shorts out.
Fuse/CB can be on NEG but best practice is POS so 'power supply' is shut off/
NEG side leaves DC on POS which can accidentally be grounded
