Circuit breaker or fuse may be an option as well, there are 2 types of fuses Slow blow and Fast blow, a slow blow will handle it's roughly it's rating for maybe a minute before blowing a fast blow or circuit breakers are nearly instant and precise. Bear in mind most motors pull 3-5 times their rated current on start up. So you can't set a quick blow fuse to the rated current. Circuit breakers are probably better bet and more convenient to reset, try one maybe 10% above the rated current, see if trips during normal usage, then go the next size up, assuming that your normal usage isn't more than the motor is designed for, best to check the motor temperature by putting your hand on it regularly, if it's getting anywhere near too hot to touch, you're overloading it, check it's temperature every time you pull up at a destination till you workout what is normal. Another idea is to install an Ammeter so you can actually see the motor current during usage.
