Beschreibung
Zusammenfassung:	A circuit protection device including a primary fuse, and a positive temperature coefficient (PTC) device and a secondary fuse electrically connected in series with one another and in parallel with the primary fuse, the secondary fuse formed of a quantity of solder disposed on a dielectric surface, wherein the dielectric surface exhibits a de-wetting characteristic relative to the solder such that, when the solder is melted, the solder draws away from the dielectric surface to create a galvanic opening.
