A fuse link is an electrical appliance. When the current exceeds a specified value, the fuse link will use its heat to fuse link the fuse link and break the circuit. The fuse link is based on the current exceeding the specified value for some time, using the heat of the fuse link to melt the melt, thereby breaking the circuit. The fuse link uses this principle to make the current protector. Fuse links are widely used in high and low-voltage power distribution systems and control systems as well as electrical equipment. As a short-circuit and over-current protector, it is one of the most commonly used protection devices. So, what are the common fuse link connection types? Next, let's take a look together.
