2.3.2 Version C
This version is particularly compact in design with an in-built line reactor.
It 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 (MCC).
The advantage here is that the cabinet unit can be sited decentrally and in the
immediate vicinity of the motor, thereby avoiding the need for long motor cables
and additional output filters.
Line fuses are required for conductor protection (VDE 636, Part 10). Line fuses can
also be used to protect the semi-conductors of the line-commutated converter
(VDE 636, Part 40/ EN 60 269-4).
The cabinet unit simply comprises a single cabinet with a width of 400 mm, 600
mm, or 1000 mm.
