Hi, I reached out to the manufacturer of this item to verify it is compatible with a 120V 60Hz single phase circuit, but did not get a reply. All similar filters that are listed from this manufacturer on DigiKey are likewise rated at 250VAC, but I don’t know if this is the operating voltage or maximum voltage.
