  • ・ Use the approximate life expectancy determined by AC-3 for the calculation.
  • ・ Note that this calculation cannot be applied to high frequency operation, AC-4.
  • ・ When the load generates an inrush current, a shorter life expectancy may occur depending on the calculation results.
  • ・ Furthermore, in consideration of deterioration due to aging, we recommend updating every 10 years when using the product in a general environment, even when the total number of cycles of the calculation has not been reached.
