Improvements to surge suppressors and other electronic devices with thermal cutoffs to reduce the risk of burning through the outer enclosure in the event electrical components such as current diverters or MOVs over heat. Improvements include barriers in between electrical components to prevent electrical contact between the components in the event of overheating of at least one component. Barriers or layers may be positioned between or around wires, conductors, thermal cutoffs, current diverters, or a combination thereof. Barriers may be fire-resistant, electrically insulating, or both, and may be made of fiberglass. Certain embodiments include revised layouts or orientations of components so that neighboring components or surfaces are at a closer electrical potential or so that exteriors of thermal cutoffs are on the protected side of the thermal cutoffs. Redundant thermal cutoffs or thermal cutoffs with non-metal or non-conducting bodies may be used and may be sandwiched between current diverters.
