Fuse, also known as current fuse, is defined by the IEC127 standard as "fuse-link". It is mainly an overload protection. If the fuse is properly installed in the circuit, the fuse will cut off the current and protect the circuit safe operation when the current abnormal is raised to a certain height and heat. Invented by Edison fuse is used to protect more than one hundred years ago when the expensive incandescent bulbs, along with the development of The Times, the fuse protection power equipment is not trained in current overheat damage, avoid electronic equipment serious damage caused by internal fault. When a circuit breaks down or is abnormal, the current increases with the current and the increased current may damage some important components in the circuit, and it may also burn the circuit and even cause a fire. If correctly placed in the circuit fuse, the fuse will be abnormal current increases to a certain height and heat, its own fuse to cut off the current, so as to protect the safe operation of the circuit.
