Thank you.
Ideally I need a three pole contactor but I need six circuits all running parallel so I could use three two pole contactors, it will see as much as 400v and 20a peak. I have wind turbines and am trying to build a passive brake in the event of a system failure. As stands if there's a power outage or something the turbines end up free-wheeling which breaks things. I want the switch to be held open by the system (which supplies 24v while active) and will automatically close if the system shuts down.
