A varistor with an alloy-type temperature fuse is disclosed, comprising a varistor, an alloy-type temperature fuse, a closed chamber, the vristor and the alloy-type temperature fuse are provide in the closed chamber, with one surface of varistor being close to one surface of the temperature fuse, the leads of them extending outside the closed chamber; the closed chamber is provide with the alloy flux. In the invention, varistor and temperature fuse are integrated, so that the velocity of heat transfer is fase, installation is facility in use.Under the action of the flux, the melted alloy may shrink toward two leads rapidly, becoming two balls, according to different requirement, chosing different melting point and different size of the alloy, matching the varistor of different current, a variety of specification of the varistor can be made by the invention, and can be applied broadly. |
