Hawke Power Ex connector

Hazardous Area Connector

Tamb: -40°C to +60°C. II2 GD Exdb IIC Extb IIIC Db T85 IP66, 67 & DTS01 deluge protected.

Overview

The Power range of connectors have been designed specifically for the extremely demanding requirements of higher power applications.

Inserts are available with 1 to 4 contacts with a conductor acceptance range of between 50mm² and 630mm² operating up to 780A and 750V as standard. Other voltages available on special request.

Power Connector Dimensions

For connector plugs and connector receptacles, cable glands are required to terminate incoming cables. These can be selected from the cable gland section of our website. These cable glands include but are not restricted to 501/453/Universal and the ICG 653/Universal.

Power 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).

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:

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).

W	N	R	Current (Amps) I
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.
