  1. Value of DC inductive loads tabulated above are the ones where stationary contact side is of positive polarity. However, where used at values more than rated operational current, opposite polarity can extend life. For details, contact Yaskawa at 1-800-YASKAWA (927-5292).
  2. Values in parenthesis are where opposite polarity is implemented.
  3. Where DC light load such as relay is utilized, opposite polarity may reduce the life expectancy.
  4. DC electrical life for R24U and R25U is based on a time constant of 40ms.
