@check that sounds like a perfectly wired whole house surge suppression.
Moving all of your home circuits to a new panel is not a trivial amount of work. Putting a surge suppressor in the now empty main panel next to the main breaker is electronically exactly what one wants to do.
Time is everything with surge suppression, and given the basically fixed speed of electrons in wires, time is distance. So putting the whole house surge suppressor as close to the incoming power as possible, and moving all of the other circuits into a separate panel, beyond a transfer switch puts them far away and gives the surge suppressor as much time as possible to react and clamp the voltage spike by shorting the surge to ground. The greater amount of electrical surge (energy) that the suppressor can short to ground, the more likely it is that your man breaker will open, putting up an even larger barrier to the surge. (Which it did in your case)
Thanks for sharing.
All the best,
Peter
