I doubt it.


It doesn't look 30A capable - you need at least 25A for 7Kw

The one in the photo has Omega markings and looks like this:

It has a 45A rating, and unless you can convince me otherwise it will be
continuously rated.


That's a cooker switch or better, and cooker switches don't have to meet
continuous load.

Can you provide a cite for this? It's not what I would expect. I could
of course be wrong.

Id go for a more industrial thing

and underrate it like fanny.

Looks OTT to me and intended for 3-phase and neutral, but YMMV.
