Front view technical drawing of a Siemens SIVACON S4 low-voltage switchboard showing the busbar configuration between QGBTA and QGBTB with a tie connection. The system features nine panel sections with a 1600A main busbar rated for 50kA short-circuit current (1s).
Main Busbar Specifications:
– Main busbar cross-section: 2x30x10mm per phase
– Neutral busbar cross-section: 2x30x10mm
– PE busbar cross-section: 2x20x5mm
– Top-front mounting position
Vertical Busbar Configurations:
– Outgoing sections: Cascaded desgin with 1190mm/1280mm rated current
– Busbar section: Non-cascaded design with 1950mm rating and 4x20x10mm cross-section
– Cable sections with N/PEN (30x10mm) and PE (40x5mm) conductors
The drawing depicts the complete power distribution scheme with outgoing sections, cable connections, and tie arrangements in a modular format according to Siemens SIVACON S4 switchboard standards.
