Special operating modes of residual current devices
Residual current devices also function in 1 and 2-phase operation. They are unrestricted in
functionality, including the test circuit, if at least 2 conductors are connected (2-pole
operation).
The phases can be selected freely.
Please note the following:
1.
Adhere to the permissible rated operational voltage.
2.
If a connection to the N pole (N) is made in a 4-pole MCCB-RCD assembly, the current
setting of the N pole determines the maximum current carrying capacity of the circuit.
