Note :
1. This is the maximum voltage that may be continuously supplied to the resistor element, see “IEC publication
60115-8”
2. Max. Operation Voltage : So called RCWV (Rated Continuous Working Voltage) is determined by
RCWV = RatedPower ×Resistance Value or Max. RCWV listed above, whichever is lower.
