Self recovery fuse is a special material made with automatic recovery function. After a circuit failure, the current increases, and the self recovery fuse will change its structure to block the current, achieving the effect of protecting the circuit. Some people think that installing a self restoring fuse in the circuit can automatically solve the problem of circuit faults. Next, the editor will answer for everyone.
Although self restoring fuses can protect circuits from being damaged by overcurrent, they cannot completely solve the problem of circuit faults. After a circuit malfunction occurs, the fuse blocks the current, and after a period of time, it will automatically restore its own structure and reconnect the circuit. If you do not solve the problem of an increase in current caused by a circuit malfunction, the self recovery fuse will operate again and again until the fuse is damaged.
So can self restoring fuses solve circuit faults? In fact, self recovery fuses are only suitable for unstable working environments in some circuits. If you want to keep the circuit disconnected during a circuit failure, then using a disposable fuse is more suitable. Moreover, if there is a circuit malfunction, if you want to replace a disposable fuse, you must first find the cause of the circuit malfunction, and then replace the fuse circuit to ensure normal use. Overall, each type of fuse has its own advantages and disadvantages, and selecting the appropriate fuse based on the actual working situation of the circuit is the safe approach
