6-630A TDFNH Serise Fuse

The core function of a fuse is overcurrent protection. It is the simplest, most effective, and most economical passive protective component in a circuit. When an abnormal high current (overload or short circuit) occurs in the circuit, it automatically cuts off the circuit through self-sacrifice, thereby protecting equipment (such as household appliances, motors, circuit boards) from burning out, preventing overheating that could lead to fires, and ensuring the safety of the entire electrical system.
