I am currently looking at some multi-conductor connectors that will handle reasonably high currents (approximately 30 A at 24 v). When reading datasheets, I see that the connectors have both a maximum current and a maximum voltage. For example,
Voltage Rating: 600 VAC / Current Rating: 9 Amps Max. in 2-position applications.
I am having a hard time interpreting this. My understanding is that the maximum current is dictated by the resistance of the pins. My intuition is that this means that it would be safe to use the conector for any application that draws less than (9 A)(600 V) = 5.4 kW of power as long as the voltage does not exceed 600 VAC.
Is this true? If so, why isn't there a single "maximum power" rating? If not, can you explain how to interpet the rating at different voltages?
