Highest verified across the families researched. The rating scope under Facts says which model each figure describes.
Facts
Source per value- Product lines Named switchgear/switchboard families or assembly types verified on the cited page; semicolon-separated where appropriate.
- Custom MV/LV switchgear; transformer-integrated switchgear 1
- MV voltage kV Highest rated or maximum-design voltage among the specific MV products researched, not a guaranteed company-wide maximum. See rating_scope; do not combine independent maxima into an orderable configuration. HV-only variants are excluded.
- 52 1
- MV current A Highest published busbar/assembly continuous current among the researched MV products; forced cooling or special configurations may apply. Separate load-switch and component limits are identified in rating_scope.
- Not published
- MV short-circuit kA Highest sourced symmetrical fault-breaking or short-time withstand rating for the researched assemblies; these are different duties. Use the cited source and rating_scope for the applicable duty, duration and voltage. Never infer interrupting capacity from bus bracing.
- Not published
- MV load-switch current A Continuous/load-dropping current of the referenced MV switch, distinct from the main busbar rating.
- Not published
- MV self-cooled current A Current explicitly supported without forced cooling for the referenced model.
- Not published
- LV assembly current A Maximum verified main busbar or assembly rating for the researched LV switchgear/switchboard; incoming breaker ratings may be lower. Does not imply an MV offering.
- 5,000 1
- LV voltage V Rated operating voltage of the referenced assembly; not its insulation or impulse-withstand voltage.
- 1,000 1
- LV withstand kA Published assembly/main-bus short-time withstand rating; source gives duration. Not a breaker interrupting rating.
- Not published
- Bus bracing kA Published bus bracing rating; source-specific cycle duration applies. Not an interrupting rating.
- Not published
- Withstand duration s Duration associated with the referenced withstand-current rating.
- Not published
- RMU voltage kV Maximum published voltage of the specifically researched ring main unit family.
- Not published
- Standards and certifications Only standards explicitly named by the source; applicability and optional listings are preserved. Repeated facts may document separate standards with separate source URLs.
- IEEE C37.20.2; IEEE C37.20.3; IEC 62271-200 (MV); UL 1558; UL 891; IEC 61439 (LV) 1
- SF6-free MV True only where an SF6-free MV assembly/design is explicitly supported. Applies to a specific product, not the entire vendor portfolio. Missing is unknown, not false; SF6-free need not mean fluorine-free.
- Not published
- SF6-free product Named SF6-free product, insulating medium and limits where established. Announced or unavailable variants are identified.
- Not published
- Insulation technology AIS = air insulated; GIS = gas insulated. Solid/vacuum technologies and gas identity are stated where sourced; vacuum interruption alone does not prove SF6-free insulation.
- AIS; GIS; solid insulation options 1
- Data center offer True where the cited first-party source explicitly markets or reports supply to data centers. It does not prove that every listed model/rating is installed in one. Missing is unknown, not false.
- Yes 1
- Data center evidence Company-level exposure, trade-press reference, or limited evidence distinguished from a verified specific MV/LV installation. Research limitations are stated explicitly; do not treat these records as proven model-level data-center references.
- Not published
- Data center project Named or anonymized vendor-disclosed order, value, timing and scope; not attributed to a specific product unless the source does so.
- Not published
- Manufacturing locations Verified manufacturing countries/cities or explicitly scoped acquired manufacturing network; planned facilities are labeled as such. Repeated facts can cover separately sourced facilities.
- Not published
- Capacity expansion Announced investment, location, timing and output change where disclosed; distinguish announcement, planned start and confirmed operation. Amounts retain original currencies.
- Not published
- Published manufacturing capacity Vendor-published throughput or manufacturing footprint, scoped to facility/product/date where known; not independently audited.
- Not published
- Enclosure and installation options Published indoor/outdoor, walk-in, NEMA/type or mounting arrangements; model-specific availability applies.
- Not published
- Assembly construction Published metal-clad/enclosed, drawout or factory-assembly characteristics.
- Not published
- Internal separation Published IEC internal separation form and type for the referenced LV assembly.
- Not published
- Service continuity category Published loss-of-service-continuity classification of the referenced MV assembly.
- Not published
- Ingress protection Published IP code for the referenced product; not generalized to all products.
- Not published
- Controls Named control system and supported transfer/control modes.
- Not published
- Control capacity Published count of controlled switches/breakers or other control limits.
- Not published
- Supply and integration options Published assembly, modular integration, or partner supply scope; does not convert component-only suppliers into assembly manufacturers.
- Not published
- Ownership or brand relationship Verified parent/brand relationship and effective date when stated; records represent buyer-facing manufacturing businesses, not necessarily independent corporate groups.
- Not published
- Relevant acquisition Completed acquisition and stated transaction value/date, preserving adjustment qualifications.
- Not published
- Rating scope and qualifications Model-specific limits, cooling, options, source discrepancies and distinctions between bus, breaker and switching ratings. Consult before comparing numeric maxima.
- The switchgear page states MV up to 52 kV and LV up to 1000 V / 5000 A for custom assemblies; it names no MV model and publishes no kA rating. 1
- Availability or verification note Published pilot, coming-soon, certification-in-progress or lead-time qualification. Marketing lead times are not contractual commitments.
- Published standard order lead time: 8–12 weeks from order confirmation to factory completion; complex custom projects take longer. 1
- Voltage segment MV when a medium-voltage (1 to 52 kV) switchgear rating is published, LV when a low-voltage assembly rating is, both when the supplier publishes each. Derived from the rating fields.
- MV and LV 1
- HQ country Country of the supplier's headquarters or brand owner, from the company page.
- China 1
- HQ region Region of the supplier's headquarters or brand owner.
- Asia-Pacific 1
