These could be triggered by a conventional circuit. I've used them to handle a couple kilowatts of RF. Trigger time is in the low milliseconds.
There may even be quicker ones. Contacts are vacuum sealed and very tough. There are RF types and high current DC types. Either should handle anything you can throw at them.
