Sid Harvey Remanufactured R75-52R

• Remanufactured with 100% pure, solid silver pyrostat contacts for longer on-the-job service life
• Backed by 2-year warranty
• All new stack relays contain brass contacts covered with a slight silver plating, it wears off as the contacts open and close, exposing the brass surface over time, the exposed surface is a poor conductor and may result in relay failure and nuisance callbacksSid Harvey Item #:R5R: Replaces Part #:'s : 0R541R,
