Line Connection Via A Ground-Fault Circuit Interrupter - Siemens SINAMICS S120 Equipment Manual

2.8.5

Line connection via a ground-fault circuit interrupter

In addition to protective measures against direct and indirect contact, selectively tripping
AC/DC-sensitive residual-current circuit-breakers (Type B) can be used.
Danger
Residual-current circuit-breakers alone are not permissible to provide protection against
direct and indirect contact.
Note
A direct connection to a power system with selectively tripping AC/DC-sensitive residual-
current circuit-breakers is only possible with the 5 kW, 10 kW, 16 kW and 36 kW Line
Modules because suitable residual-current devices with higher ratings are not available as
qualified products.
