Can someone explain a reason why putting 2 contacts in series would increase switching ampacity?

Your answer, the current rating is based Not on what the contacts can safely carry but on the current that the contacts can safely interrupt.

The NEMA ratings for the relay contacts show "Thermal Continuous Test Current" and then there is make / break current. The break current is much lower than the thermal. Can someone explain the thermal?

That's what I would assume too - but I keep getting surprised with standards and ratings from other parts of the world so I guess I'm getting cautious in my old age.
