Is it possible to use a 1P+N surge protection device to protect 2 live lines in a system. i.e. instead of using it on a live and neutral, is it possible to use it on 2 lives instead?

We do not advise to use this configuration because this way, you won't protect the 2nd phase against overvoltage (you will have no Varistance in phase 2). Moreover, we won't guarantee the end of life in case of short-circuit. We advise to use a 2P configuration with MCB.
