Front view layout of a Siemens SIVACON S4 low-voltage switchboard featuring a comprehensive busbar configuration. This drawing details six sections including incoming/outgoing section, cable exit, and 1250A-rated sections.
Technical Specifications:
– Main busbar system: 2500A rated current
– Short-circuit withstand (Icw): 50kA for 1 second
– Main busbar cross-section: 4x40x10mm
– Neutral busbar: 4x40x10mm
– PE busbar: 2x20x5mm
– Main busbar position: Top (front)
Vertical Busbar Systems:
– Section 2: Non-cascaded type, 2410A rated, 4x40x10mm cross-section
– Section 3: N/PEN with 30x10mm and PE with 40x5mm cross-sections
– Section 4: Cascaded type, 1190A rated, 2x30x10mm cross-section
All six sections maintain consistent 2500A main busbar capacity with top-front positioning. The switchboard follows Siemens industrial electrical distribution standards for power distribution applications.
