Calculation conditions

approximate values
vertical mounting inside a building (no forced air flow)
max. air temperature 40 °C
operating temperature of the connector 90 °C
conductivity above 101% IACS
direct current (DC)

They apply to the PG, PE and SM tables. The PAL table is based on 70 °C and 57% IACS; the SE table gives the current at a temperature rise ΔT.
