Line Connection Modules

Design

Line Connection Modules contain the line-side components as main circuit breaker and fuse switch-disconnector or
circuit breaker and provide the connection between the plant power system and the Line Modules.
Various frame sizes are available depending on the input power rating.

Example configuration of Line Connection Modules in frame sizes FL, GL/HL, JL, KL/LL
Different frame sizes have been developed to meet the requirements of different applications which vary in terms of
their power demand and optional component complement.
Main breakers with fuse switch-disconnectors are used in frame sizes FL, GL and HL. Type 3WL circuit breakers are
installed in Line Connection Modules with higher output power ratings. The incoming supply is fed in from below on
all units. The supply can be brought in from the top, but requires an additional cabinet.
Line Connection Modules are designed such that they do not need a cabinet fan for operation at standard ambient
conditions. Partitions and air-flow guides inside the cabinets obviate the need for fan cooling.
When combined with a Basic Line Module in combination with degree of protection IP23, IP43 or IP54, frame sizes
JL, KL and LL are equipped with a fan to provide extra internal cooling. On these models, the fan is mounted in the
hood, protected by fuses and connected separately to a clamp in the terminal area.
