Technical Information
Both the design requirements and the current-carrying capacity connector must checked the user when selecting connectors.
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.
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., surrounding air temperature 80°C (176°F).wago.
