1)
Outside dimensions are valid for versions with 4 barriers. Dimensions for versions with
3 and 2 barriers are available on request.
2)
The reduction factors are based on the rated current I
e
and an ambient temperature of
35°C (24-hour average). In the event of temperature deviations, reduction factors
should be adjusted accordingly.
3)
Mounting position horizontal edgewise:
LXA/LXC (trunking conductor)
Use of LXC at 6300 A
For requirements with rated currents of 6300 A, it is necessary to use two single systems
LXC07 (I
e
= 3200 A) in parallel. In the installation manual "Installation with LX System"
(order number: A5E01120816) you will find solution suggestions on how to use external
copper material to implement an electrical connection for parallel switching on the infeeds
such as non-Siemens distribution boards or transformer connections.
Please contact the relevant product manager for more detailed information about
dimensioning and current carrying capacity.
