The special-purpose GFCI category is for applications where equipment grounding is provided by the NEC or where the voltage is greater than 150V. Specialty GFCIs trip when the current to ground has a value of 15 to 20 mA.
Overload means an excess current drawn, which will lead to tripping of the circuit breaker once the current exceeds 5 times the rated MCB current value within a tenth of a second (depending on the Type of MCB). When your electric load is faulty and there's a short circuit, a lot of current is drawn -> MCB trips. But an electric shock to a human being may not always draw an excessive current that is so high to trip the MCB and protect you. This is where RCCB comes in.
