A switch and an isolator are not the same thing. *Isolators are meant
to be opened under no-load conditions.
They won't last long used as switches which will interrupt their rated
current.

True, I was just meaning that it isn't an overload protection device.

It's not actually clear whether the device in question is intended to
*switch* the current or not. *Given that it's a solid state device it
might actually be able to switch while on load without much distress.

A solid state device is not an isolator. The circuit has to be
phyisically broken in both poles to be considered to be isolated.
