Ratings
(1)
Rated Continuous Working Voltage (RCWV) shall be de ter mined from RCWV=
√
Power Rating × Re sis tance Values, or Limiting Element Voltage list ed above, whichever less.
(2)
Overload Test Voltage (OTV) shall be determined from OTV=Specified Magnification (refer to performance) × RCWV or Maximum Overload Voltage listed above, whichever less.
(3) Use it on the condition that the case temperature is below the upper category temperature.
