That’s likely due to power-dissipation (heat-dissipation) limitations. Run it too fast, and you get a liquid-switch.

Better thermal characteristics is the fix for that. Bigger, more thermally conductive, electrodes seated in a material that can draw the heat away. Or more switches, or banks of switches operating in sequence.

There are likely few off-the-shelf solutions for high-rate, high-current, high-voltage switches. What seems to be available is you get a trade off between the the first two parameters.
