(1) Rated Continuous Working Voltage (RCWV) shall be determined from RCWV= Power Rating × Resistance Values, or Limiting Element Voltage
listed above, whichever less.
(2) Overload (Short-time Overload) Test Voltage (SOTV) shall be determined from SOTV=2.5 × Power Rating or max. Overload Voltage listed above
whichever less.
