Question: What is the maximum voltage of the self-recovery fuse?

Answer: Surge thyratron and discharge tube are used for transient overvoltage protection, while polymer positive temperature coefficient self-recovery fuse can only be used for overcurrent protection. So how much maximum current and voltage can they withstand? Generally speaking, the traditional overvoltage protection device is mainly used for transient overvoltage protection, but it is also suitable for long-term voltage stabilization that does not exceed its rated power. Self-recovery fuse can be used not only for over-current protection, but also for over-temperature protection or protection under the combined action of current and temperature. In addition, it can also be used together with IC for temperature detection and protection of feedback temperature signal. At present, the maximum voltage that the self-recovery fuse can withstand is 600Vrms, and the maximum holding current is 15A；. The maximum voltage of PPTC for automobile is 60Vdc, and the maximum holding current is 15A.
