I think those Australian symbols look slightly different to the ones I'm used to - but the basics look the same - i.e. a "bar" across the fixed contact indicate an isolation gap when open and the "x" overcurrent protection - so yes a simple CB. As yours symbol seems only to show a single switching element I would suspect the main MCCB part doesn't switch N (I can't see any N terminals on the one you linked to either, despite the link title).
The plain unit to the left of each MCCB - is that just a blank or might it be an add-on contact for N? Is the side label you show from the N block (if that's what it is) or from the main MCCB?
Most standards seem to require things that they apply to be marked with their standard number - so I suspect this would be most easily solved by removing the cover....(but 60947 sounds entirely plausible).
I don't think there's any general requirement for an isolator to have an in-built means of locking-off - it may need some add-on gadget or rely on locking the overall case or just not be intended for isolating remote items.
