How to do the overload protection？The article below  introduces it.

Power supplies should have some type of overload protection. Overload protection is important to protect the electronic equipment hooked up to the power supply and to also prevent overheating, which could potentially lead to an electrical fire. Fuses and circuit breakers are two of the more frequent mechanisms used for overload protection.
Fuse:A piece of wire is connected between two metal ends. The two metal ends of the fuse are connected by either a tube of glass or plastic which surrounds the wire. If too much current flows, the wire overheats and melts. This interrupts the power supply, and the equipment stops working until the problem that caused the overload is identified and the fuse is replaced.

There are two types of fuses, slow-blow and fast-blow. In a fast-blow fuse, the wire inside the fuse will melt if the current exceeds the rated current, even if it is just for a fraction of second. This concise process is important in electronic equipment where even a small spike in the current could damage the equipment. A slow-blow fuse is designed to only melt when there is a continuous overload. Slow-blow fuses are ideal for motor systems.

Circuit breakers:One benefit of using a circuit breaker as opposed to a fuse is that it can simply be reset instead of having to constantly replace the blown fuse. A circuit breaker works once an overloaded current causes some element to heat and trigger a spring which shuts the circuit down. Once the element cools, and the problem is identified the breaker can be reset and the power restored.
