Legrand
Makes low-voltage distribution systems and devices for buildings and data centers. XL3 HP 6300 is its modular power switchboard assembly system.
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.
- XL3 HP 6300; DMX3; DPX3 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.
- Not published
- 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.
- 6,300 1
- LV voltage V Rated operating voltage of the referenced assembly; not its insulation or impulse-withstand voltage.
- Not published
- LV withstand kA Published assembly/main-bus short-time withstand rating; source gives duration. Not a breaker interrupting rating.
- 100 1
- 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.
- IEC EN 61439-1 and -2 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.
- Not published
- 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 2
- 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.
- Up to Form 4b 1
- 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.
- Modular enclosure, busbar and protection system for building LV switchboards 1
- 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.
- Not published
- Availability or verification note Published pilot, coming-soon, certification-in-progress or lead-time qualification. Marketing lead times are not contractual commitments.
- Not published
- 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.
- LV 1
- HQ country Country of the supplier's headquarters or brand owner, from the company page.
- France 1
- HQ region Region of the supplier's headquarters or brand owner.
- Europe 1
