              IH = Hold current : maximum current at which the device will not trip at 25oC still air.
              IT = Trip current: minimum current at which the device will always trip at 25oC still air.
              Vmax= Maximum voltage device can withstand without damage at rated current.
              I max = Maximum fault current device can withstand without damage at rated voltage.
              Ttrip=Maximum time to trip(s) at 5*IH.
              R min = The smallest zero power resistance under the ambient temperature of 25℃.
              R max = The biggest zero power resistance in the ambient temperature of 25℃.
              R1max =Maximum device resistance one hour after it is tripped at 25oC.
