Buccaneer for Power 46

Current Carrying Capacity

BUCCANEER FOR POWER

6000 Series Buccaneer

The thermal properties of the materials used in the

construction of a connector limit the current carrying

capacity. There are a number of factors that determine

the amount of current that can be handled: contact

spacing, size of cable, ambient temperature and the

heat that is generated by the current passing through

the connector.

The maximum current varies with different contact

layouts, and because of these factors it is necessary

to produce de-rating curves for each pole variant. This

de-rating curve is specified in the standard IEC 60512

part 3. De-rating curves are plotted for each contact

carrier combination with the current being carried

simultaneously by all contacts. These graphs show the

heat rise generated as the current is increased.

The red line indicates the direct correlation between

current applied and the measured temperature rise

within the connector. The dotted blue line shows rated

current and the green line is derived by applying a

factor of 0.8 to the original plot data to give a de-rating

curve. The dashed blue line shows the rated current.

The shaded area under the 0.8 curve shows the

permitted operating area, and allows safe current vs

ambient temperature characteristics to be determined.
