BA/BB Varistors

Littelfuse BA/BB Varistors 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. The varistors have similar package construction but differ in size and ratings. The BA models are rated from 130VM(AC) to 880VM(AC) and the BB models from 1100VM(AC) to 2800VM(AC).
