| Zusammenfassung: | A protection device includes a meltable conductor, an electrode set, and a heating element. The meltable conductor has a core metal layer and a bottom covering layer with low melting point. The core metal layer has a first low melting point metal layer, a second low melting point metal layer, and a high melting point metal layer laminated therebetween. The bottom covering layer with low melting point is disposed on a bottom surface of the core metal layer. The electrode set has a first electrode and a second electrode respectively connected to two terminals of the meltable conductor. The heating element is disposed under the bottom covering layer, thereby heating up and blowing the meltable conductor in the event of over-voltage. |
