description	A circuit protection device including a PTC device having a PTC element, first and second electrodes disposed on opposing first and second surfaces of the PTC element, respectively, first and second chip fuses disposed on the first and second electrodes, respectively, the second chip fuse electrically connected in series with the PTC device, and the first chip fuse electrically in connected parallel with the PTC device and the second chip fuse, the first chip fuse having a lower electrical resistance than the PTC element when the PTC element is in a non-tripped state, wherein a fusible element of the first chip fuse has a first melting temperature and is configured to carry a current higher than the PTC element can carry without tripping, and wherein a fusible element of the second chip fuse has a second melting temperature that is greater than the first melting temperature.
