Powerex logo Calculations

To select the shell size of the connector, it is essential that you calculate the dissipated wattage of the arrangement. This ensures that the arrangement does not exceed the maximum permitted temperature classification with regard to the upper ambient temperature for the area of installation. (please refer to table 1 below for the maximum allowable dissipated wattage per connector size).

TABLE 1

Dissipated Wattage Calculation

Equation definitions:

W = Dissipated wattage factor of the connector

N = The number of conductors to be terminated/number of contacts required. (Note: A contact comprises of a pin and socket).

I = The current requirement per contact. (Note: This must be equal to or less than the maximum current rating of the contact, as shown in table 2 above).

R = The combined cable and contact resistance (see table 2 above).

Values pertinent to these definitions must then be input into the relevant fields below to calculate the dissipated wattage (W) of your chosen arrangement:

1. W = N x I ² x R
N I R Dissipated Wattage
(Watts)
W

Note: The result must be lower than the maximum figure shown in table 1 above, for the appropriate temperature class and ambient temperature).

e.g. T6 40°C ambient application with 4 x 95mm² conductors running at 160 amps.
N = 4 contacts
I = 160 amps
R = 0.000283 ohms (95mm² soldered combined cable and contact resistance)

Therefore W = 4 x 25600 x 0.000283 = 28.9 watts.
Therefore an Ex63P Connector should be specified for this application as the shell size can accommodate the required 4 x 95mm² pin / socket inserts (see insert selection table) and the resultant dissipated wattage (28.9 watts) is below the maximum permitted 30.2 watts (see table 1 above).

This equation can also be transposed to facilitate the calculation of the maximum number of conductors permitted in your selected connector (calculator 2 below ) and the maximum allowable current within the upper ambient temperature of your location (calculator 3 below).

3. maximum current formula

Note: The result must not exceed the maximum current rating of the contacts (see table 2 above)

Note: Unless otherwise requested, connectors will be marked as T5 with an upper ambient temperature of +40°C.
