Overview of V571DB40

The DA and DB Series transient surge suppressors are heavy-duty industrial metal-oxide varistors designed to provide surge protection for motor controls and power supplies used in oil-drilling, mining, and transportation equipment.These UL-recognized varistors have identical ratings and specifications but differ in case construction to provide flexibility in equipment designs.DA series devices feature rigid terminals to insure secure wire contacts.Both the DA and DB series feature improved creep and strike distance capability to minimize breakdown along the package surface design that provides complete electrical isolation of the disc subassembly.
