Sin,

I know that, I needed to see if the person asking the question knows what the letters mean.

In some places the same letters may mean something different.

Here in USa MCB stands for Main Circuit Breaker, for example.

The person asking the original question never did get back with what was at least what the letters meant, so I guess this thread is irrelvant.
