Home / Temperature rise of dense bus connectors
There are three forms of heat dissipation in copper busbars which occur by convection, conduction, and radiation.
As an example: if the maximum operating temperature for a connector operation is 105°C and the ambient temperature is 25°C, the maximum heat rise attributable to the connector is 105°C - 25°C =
