Metal-Oxide Varistors (MOVs) Industrial High Energy Terminal Varistors > BA/BB Series RoHS BA/BB Varistor Series Description BB Series The BA and BB Series transient surge suppressors are heavy-duty industrial Metal-Oxide Varistors (MOVs) designed to provide surge protection for motor controls and power supplies used in oil-drilling, mining, transportation equipment and other heavy industrial AC line applications. These varistors have similar package construction but differ in size and ratings. The BA models are rated from 130 to 880V . The BB models from 1100 to 2800V . BA Series M(AC) M(AC) Both the BA and BB Series feature improved creep and strike capability to minimize breakdown along the package surface, a package design that provides complete electrical isolation of the disc subassembly, and rigid terminals to Agency Approvals ensure secure wire contacts. See BA/BB Series Device Ratings and Specifications Table Agency Agency Approval Agency File Number for part number and brand information. UL1449 E320116 - for BA Series only.
