Residual current circuit breaker (RCCB)

Note
The SINAMICS V20 inverter has been designed to be protected by fuses; however, as the
inverter can cause a DC current in the protective earthing conductor, if a Residual Current
Circuit Breaker (RCCB) is to be used upstream in the supply, observe the following:
• All SINAMICS V20 single phase AC 230 V inverters (filtered or unfiltered) can be
operated on a type A
RCCB.
• All SINAMICS V20 three phase AC 400 V inverters (filtered or unfiltered) can be operated
on a type B(k) 300 mA RCCB.
• SINAMICS V20 three phase AC 400 V inverters (unfiltered) FSA to FSD and FSA
(filtered) can be operated on a type B(k) 30 mA RCCB.
• When multiple inverters are in use, one inverter must be operated on one RCCB of the
corresponding type; otherwise, overcurrent trips will occur.
To use a type A RCCB, the regulations in this FAQ must be followed: Siemens Web site
