MV Static Contact Assembly

MV static contact assembly is a complete sub-assembly including the static contact element, mounting hardware, and supporting components, supplied as a single unit for MV switchgear OEMs who prefer to source the static contact side as a complete module rather than assembling component-by-component.

For just the static contact element, see MV Switchgear Static Contact. For 630A-specific static contacts, see Static Contact 630A. For arc-exposed static contacts, see CuW Static Arc Contact.

Applications

• Static contact sub-assembly for new MV VCB builds at 12 / 24 / 40.5 kV
• Drop-in replacement assemblies for refurbishment programs
• Sub-supply to MV switchgear OEMs sourcing the static side as a complete module
• Specialty static contact assemblies for non-standard switchgear builds

Technical Notes

For OEMs sourcing the static contact as a complete sub-assembly, the per-part-number QC is simpler than component-by-component qualification: one part number covers the contact element, the mounting interface, and the supporting hardware. For service / refurbishment, replacing the complete sub-assembly is often easier than rebuilding the static contact from components in the field.

The assembly's mounting interface, bolt pattern, locating features, electrical termination, has to match the switchgear cabinet design. For new OEM programs, supply the cabinet interface drawing along with the contact spec; we'll match the assembly to fit. For refurbishment, supply the original drawing or sample of the assembly being replaced.

For arc-resistant variants, the static contact element can have a pre-brazed CuW tip while the rest of the assembly is standard. Specify the CuW grade and tip geometry along with the assembly drawing.

Sourcing & OEM

Custom MV static contact assemblies to your drawing are routine. Specify the contact material, mounting hardware, plating, and any CuW tip requirements; contact us for a project-specific quote.
