Functioning current-carrying capacity curve per 60512-5-2 shown application using current-carrying capacity curve for the
X-COM®-SYSTEM:
This application requires each pole 4-pole connector subjected load Based the basic curve determined for this pole
number with conductor cross section mm², has been determined the maximum surrounding air temperature 42°C (107.g.6°F).
This data depends the following factors: connected conductor cross section, surrounding air temperature, number simultaneously
loaded poles, connector’s internal resistance, well PCB layout and connector materials required. The
current must reduced higher surrounding air temperatures, e. accordance with IEC/EN 60512-5-
2, the relationship between current, surrounding air temperature and temperature rise the connector’s upper temperature limit illus-
trated via current-carrying capacity curve.wago.
