"Novel Designs for Packaging Circuit Protection Devices" Joseph M. Ratell Abstract of the Disclosure Circuit protection devices which comprise a PTC conductive polymer element and an enclosure, and which are less likely to cause damage to other electrical components through release of carbonaceous dust. On the interior surface of the enclosure, there is a pro- jection or other disconformity which is spaced apart from the electrodes and which provides a site for arc initiation. In this way, the danger of erosion creating a hole in the enclosure is reduced. Prefer- ably each of the electrodes is surrounded by a projection.
