This technical contribution describes a conventional measurement setup for the determination of current carrying capacity of connectors specifically designed for heavy current applications in connection with printed circuit boards. In this model arrangement the physical factors influencing current carrying capacity are examined in terms of the design of conducting tracks and the layer construction of the printed circuit board. In the course of the electrical-thermal simulation of a measuring routine utilizing the finite element method, the authors discuss the various influencing parameters. In this context, the individual elements of the model such as the input of individual wires, the printed circuit board itself with its conducting track widths and the design of the connector are of particular significance. The simulation model selected is in continued use in order to determine the current carrying capacity of connectors with parallel-switched contacts. Here, particular emphasis is on discussing the influence of deviating constriction resistance of contacts connected in parallel. These parallel connected contacts with lower current carrying capacity is especially interesting for the cost efficient utilization of components for industrial applications, as the component's high number of poles provides many contacts for practical applications and thereby enables parallel switching.
