Well that clearly shows the thermal/magnetic element (square & curve zig-zag bit) is only in the line path.This should be clearer:

That shows the trip part as the 'X' crossing the live path just after the switch symbol.Crabtree single module
That shows the trip part as the 'X' crossing the live path just after the switch symbol.
I think it is often seen that a MCB/MCCB is shown just as an X on power schematics.
I think it is just one of conventions.What are the practical differences between the two schematics? I don't fully understand either, but this is a great alternative to painting the kitchen.
So RCCB really means "residual current, concealed -----"?No ----- on this image:
That is a fair point.Often the space is, nt available in older installations. In newer installs space is generally a non-issue. But I can assure from experience that once you install a CU with dual module rcbo, s you will find yourself seeking to "make the space" on your next install. I find installation time is nearly halved. Its a bit like comparing a WAGO push in to a traditional connector. They are also very convenient for testing and for faultfinding.Is a neutral busbar worth the additional space required for 2 module RCBOs?
