If we have a HE12-1A69-02 from Standex Electronics. The point is that rating is 50 W and can do up to 10,000 Volts. If used a voltage of 5 kV for a load greater than 10 mA the power would be exceeded. Or since the power of the relay not really apply cause the voltage being dispensed across the relay is essentially zero when closed. If this is true does the maximum current draw across the load is limited not by the 10 mA limited by the power calculation but by the max current draw since the relay is acting as a wire. Thus we can use the maximum current of the relay.
