Strikesorb TVSS (transient voltage surge surpression) module is the only UL-recognized surge protection device (SPD) fully tested to the complete procedure defined by the revised UL 1449 standard. Equipment that includes the module does not require further UL 1449 testing in order to meet UL Listing requirements. Strikesorb modules have passed 3-cycle testing at available short circuit currents of up to 100,000A rms. The module is comprised of a single distribution-grade metal oxide varistor (MOV) disc that provides uniform distribution of the surge current over the total area of the MOV protection element.
