Methodology
Primary sources, one link per number, a date on every row.
Where the data comes from
We read each supplier’s own product pages, datasheets and brochures, annual and quarterly filings and press releases, plus named trade press. Switchgear is specified, so datasheets come first. Every record lists its sources with the date we accessed them, and every number in the table links to the source it came from.
How we verify
Each row shows the date we last checked it. A field is filled only when a source states it; when a supplier does not publish a figure, the cell stays empty. Every rating belongs to a named product family at a named voltage: the table shows the highest figure published across the families researched, and each supplier page’s rating scope says which model it describes. Short-time withstand, bus bracing and breaker interrupting ratings are different duties and are never merged.
Corrections
Vendors and readers can send corrections to hello@switchgearsuppliers.com with a public source. We update the row and its verified date. Featured placement is paid and labelled; it never changes a row’s data or its position in the sorted table.
Reuse
The dataset is free to reuse under CC BY 4.0 with a link to switchgearsuppliers.com. Download it as CSV or JSON.
Field definitions
37 fields- Product lines
- Named switchgear/switchboard families or assembly types verified on the cited page; semicolon-separated where appropriate.
- 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.
- 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.
- 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.
- MV load-switch current A
- Continuous/load-dropping current of the referenced MV switch, distinct from the main busbar rating.
- MV self-cooled current A
- Current explicitly supported without forced cooling for the referenced model.
- 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.
- LV voltage V
- Rated operating voltage of the referenced assembly; not its insulation or impulse-withstand voltage.
- LV withstand kA
- Published assembly/main-bus short-time withstand rating; source gives duration. Not a breaker interrupting rating.
- Bus bracing kA
- Published bus bracing rating; source-specific cycle duration applies. Not an interrupting rating.
- Withstand duration s
- Duration associated with the referenced withstand-current rating.
- RMU voltage kV
- Maximum published voltage of the specifically researched ring main unit family.
- 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.
- 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.
- SF6-free product
- Named SF6-free product, insulating medium and limits where established. Announced or unavailable variants are identified.
- 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.
- 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.
- 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.
- Data center project
- Named or anonymized vendor-disclosed order, value, timing and scope; not attributed to a specific product unless the source does so.
- 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.
- Capacity expansion
- Announced investment, location, timing and output change where disclosed; distinguish announcement, planned start and confirmed operation. Amounts retain original currencies.
- Published manufacturing capacity
- Vendor-published throughput or manufacturing footprint, scoped to facility/product/date where known; not independently audited.
- Enclosure and installation options
- Published indoor/outdoor, walk-in, NEMA/type or mounting arrangements; model-specific availability applies.
- Assembly construction
- Published metal-clad/enclosed, drawout or factory-assembly characteristics.
- Internal separation
- Published IEC internal separation form and type for the referenced LV assembly.
- Service continuity category
- Published loss-of-service-continuity classification of the referenced MV assembly.
- Ingress protection
- Published IP code for the referenced product; not generalized to all products.
- Controls
- Named control system and supported transfer/control modes.
- Control capacity
- Published count of controlled switches/breakers or other control limits.
- Supply and integration options
- Published assembly, modular integration, or partner supply scope; does not convert component-only suppliers into assembly manufacturers.
- Ownership or brand relationship
- Verified parent/brand relationship and effective date when stated; records represent buyer-facing manufacturing businesses, not necessarily independent corporate groups.
- Relevant acquisition
- Completed acquisition and stated transaction value/date, preserving adjustment qualifications.
- Rating scope and qualifications
- Model-specific limits, cooling, options, source discrepancies and distinctions between bus, breaker and switching ratings. Consult before comparing numeric maxima.
- Availability or verification note
- Published pilot, coming-soon, certification-in-progress or lead-time qualification. Marketing lead times are not contractual commitments.
- 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.
- HQ country
- Country of the supplier's headquarters or brand owner, from the company page.
- HQ region
- Region of the supplier's headquarters or brand owner.
