EDGEWOUND TYPE RESISTORS

Type EWR Edgewound Resistors feature a stainless steel strip type element, wound on its edge and supported on grooved porcelain supports. Like the type CSW and type FDL, these units are through-bolt mounted on a 5/16" - 18 rod. Stainless steel terminals are welded to the element to complete this robust design.
