If that unit where smaller and had surge protection it would be perfect. That said surge protection could be a separate device. Problem is I need three of whatever model I decide on. Each rig is in the neighborhood of 1800 watts so I can't plug multiple rigs into one unit.
I listed that one because it does 20A. I believe it does does have over current protection where it switches off the port/outlet when you go over the desired amp rate you set in the web gui.
They make a larger version for both 120v and 240v. Both of these have breakers for each bank of ports. The one's that only meter the entire PDU are significantly cheaper if thats all you are looking for. Per Port amp metering is what makes these expensive.
