SIVACON

Siemens SIVACON is the power distribution and switchgear enclosure system used for low-voltage switchgear assemblies, motor control centers, and industrial power distribution panels. SIVACON S4 is the structural enclosure platform within this family, providing the mechanical framework, busbars, mounting provisions, and enclosure components for building or extending LV switchgear panels in industrial power distribution applications. SIVACON S4 panels are installed in LV switchrooms, power distribution rooms, and industrial electrical rooms across energy, process, manufacturing, and infrastructure facilities. When a SIVACON S4 enclosure component, a frame, busbar, terminal cover, or structural element, needs to be replaced or a panel extension is being built to match existing installed equipment, sourcing the correct SIVACON S4 hardware outside of standard channels can be challenging. 

PLC Direct supplies Siemens SIVACON hardware to customers sourcing enclosure components for existing SIVACON S4 installations. Our collection covers structural frames, supporting structures, and copper busbar components across the SIVACON S4 range. All SIVACON products are currently listed for sourcing inquiries; customers are encouraged to contact us to confirm availability for specific part numbers. 

Where Siemens SIVACON Hardware Is Used 

SIVACON S4 enclosure systems are used wherever a standardized, modular LV switchgear structure is required. The hardware is structural rather than control-logic-based, and replacement needs arise when panels are extended, modified, or repaired. 

Facilities and applications that rely on Siemens SIVACON hardware include: 

• Industrial LV switchrooms requiring frame or busbar replacement for SIVACON S4 panels 

• Power distribution centers in manufacturing and process plants 

• Motor control center expansions requiring additional panel bays to match the existing SIVACON S4 installation 

• Energy production and distribution facilities with SIVACON-based LV switchgear 

• Infrastructure projects that extend or modify existing SIVACON S4 panel configurations.

What to Know Before You Buy Siemens SIVACON 

SIVACON S4 enclosure hardware is dimensional and configuration-specific. Ordering the correct frame or structural component requires matching the panel bay dimensions of the existing SIVACON S4 installation. 

Current availability: SIVACON products in the PLC Direct collection are currently listed with zero units in stock across the range. This collection represents hardware that PLC Direct can source and fulfill on inquiry. Contact us with your specific part numbers to discuss availability and lead time. 

Dimensional matching: SIVACON S4 frames are available in a matrix of height, width, and depth combinations. H: 2000 mm is the standard height for the S4 range. Width and depth must match the existing panel configuration. Mixing non-matching frame dimensions in a panel row will result in structural misalignment. 

Busbar selection: The copper busbar cross-section must be sized to the power distribution application's current rating. The 50 x 10 mm cross-section (8PQ4000-0BA18) is the confirmed variant available for inquiry. Confirm that this cross-section meets the current-carrying requirement for the installation before sourcing. 

Warranty: All Siemens SIVACON hardware purchased from PLC Direct includes a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
