UI = Operate voltage at 20 °C after pre-energizing with
UI without contact current
UII = Maximum continuous voltage at 20 °C for
Tc max = 115 °C without contact loading
Operating voltage limits UI and UII depend on temperature and
can be calculated by:
UI tamb = kI · UI 20 °C and UII tamb =kII· UII 20 °C
