Resettable fuse: using metallic sodium as a melt, having high electrical conductivity at room temperature. When the circuit is short-circuit fault, short circuit current high temperature high pressure sodium rapid vaporization Xinxiang fuses, sodium vapor high impedance voltage fuse Anyang, thus limiting the short circuit current. When the short circuit current is removed, the temperature drop, sodium metal to restore the original good conductive properties. Resettable fuse can limit the short circuit current, not really breaking the circuit. The advantage is that the melt need not be replaced and can be reused. The excellent performance of the fuse circuit protection, overload protection performance in general. If it proves necessary to use a fuse in overload protection, the need to carefully match the line overload current fuse rated current. For example: 8A melt for circuit 10A, and doubles as a short-circuit protection with overload protection, overload protection feature, but this time is not ideal.
