We have seen a whole development having earth leakage as main.We pass it although stoves and nuisance tripping can cause issues down the line .So would not recommend earth leakage as main switch.

I could not see the model number of the E/L but the C/B spec sheets also has E/L on it and that brand does look like it has overload protection as well and is rated at 6kA. However, another point is, is it SABS approved?
Out of personnel experience I would say a DB must have a mains smaller then the supply mains. I recently had a call out about a light not working. After testing I decided to investigate the I ceiling for loose wires. I switched the earth leakage off, since there was no mains and looked for the fault in the ceiling. When I touched a metal conduit I received a severe shock
Back on the ground I found out that the lights were not on earth leakage but was fed from the TOP of the earth leakage. So having a mains, prefabil a two pole is best.
Just for interest sake: 30A and 40A mains and even smaller is pretty common in my valley. That however is a story for another day

According to this web site it is a 40A circuit breaker as well.
The symbol is an electromagnetic device used for the tripping mechanism, not sure the origin though.
