I want to use a solid state relay to switch a load of 24V, 25A. I have picked 2 relays that can be used:

The first one has "8 degrees C per watt" dissipation of the built in heat sink. I was never good at calculating these heatsinks, can anyone give an idea is this enough of not and how to calculate it? Simpler if possible please.
It is possible that the load is not at 25A all the time, but drops to 12 half of the time, still I think the wors option should be considered.
