Question

Can a 4 pole RCCB be single phased?

Accepted Answer

The Acti 9 four pole RCCB incomers, A9RXXXXX range cannot be single phased. This is because the test button circuit requires 400Vac for test circuit to work.
They can still be used in 2 phase/3 phase applications, for more details please contact Schneider support.
Note: The test button has to be tested regularly in accordance with wiring regulations BS7671.
