Why the RCCB is only 2P and 4P ? & Why the Vigi module is 3P ?
The RCCB must see the live phases and the neutral.
When we install the earth leakage module with the incoming breaker, it will disconnect the whole system when an earth leakage occur at any MCB.
For that the RCCB is 2P (1P+N) and 4P (3P + N)
Sometimes, the system's 220V is line to line, so we will have two live poles. To protect them against earth leakage, we will need 3P.
