Generally speaking, in the circuit protection plan, whether to use blown fuse or self-recovery fuse components is used to protect the circuit. This is a problem that technical engineers should consider carefully when choosing circuit fuses. When selecting models, our technical engineers must know the performance parameters of fuses, so as to accurately select the protective equipment suitable for their own circuits. Then, let's learn about the "performance" difference between self-recovery fuse and blown fuse, as follows.
Self-healing fuse differs from blown fuse in "performance": in terms of internal resistance, their resistance values are different. The internal resistance of the fuse is relatively small, while the resistance of the self-recovery fuse is relatively large.
The "performance" difference between self-recovery fuse and blown fuse is two: for current sensitivity, the blown fuse has high sensitivity to current, and the blown fuse blows quickly, which reflects the performance of high safety protection response. While the self-recovery fuse is relatively low.
There are three differences in performance between self-recovery fuse and blown fuse: in the speed of running time, the running time of blown fuse is relatively fast, while the running time of self-recovery fuse is relatively slow, which can reflect that self-recovery fuse has excellent impact resistance;
"Performance" difference between self-recovery fuse and blown fuse 4: Comparison of leakage current. The fuse has no leakage current, which shows high reliability in the circuit, and the self-recovery fuse has leakage current.
The "performance" difference between self-recovery fuse and blown fuse is five: from the perspective of safety performance, the safety performance of blown fuse is higher than that of self-recovery fuse;
Difference of "performance" between self-recovery fuse and blown fuse 6: In terms of application range, the application range of blown insurance is relatively wide, and many electronic products use blown fuse to protect circuits, but the application range of self-recovery fuse is relatively small;
"Performance" difference between self-recovery fuse and blown fuse VII: Recoverability of fuse The blown fuse has no recovery performance, but the self-recovery fuse is characterized by recovery performance. Due to the recoverability of fuses, maintenance and service costs can be reduced;
