Version C - Siemens SINAMICS G150 Operating Instructions Manual

2.3.2

Version C

This version is particularly compact in design with an in-built line reactor.
This version can be used, for example, when the power supply connection components,
such as the main contactor and main circuit-breaker with fuses for conductor protection and
semi-conductor protection, are installed in an existing central low-voltage distribution unit.
Line fuses are required for conductor protection. Line fuses can also be used to protect the
power semiconductors of line-commutated converters (IEC 60269).
CAUTION
The protection of the cabinet units with type 3NE line fuses is urgently recommended. The
recommended fuses can be found in the technical data.
The cabinet unit simply comprises a single cabinet with a width of 400 mm, 600 mm, or 1000
mm.
