Schneider Electric Canalis
Manufacturer: Schneider Electric
Schneider's own IEC busbar trunking family - not sold in the US or Canada, unlike Square D I-Line
This model is part of SecondWatt’s busway research catalogue. Specifications and price observations are included where supported by sources. Equipment availability and commercial terms require confirmation.
Schneider Canalis busbar trunking specs, IEC ratings, and pricing data, plus why US data center buyers should source Square D I-Line instead of Canalis.
Schneider Electric's own US support FAQ states it plainly: "Canalis refers to a line of Telemecanique brand busway or 'busbar trunking' as it is referred to in Europe. It is presently not available for sale in the U.S. and Canada." A North American data center buyer searching "Schneider busway" should go to Square D I-Line and I-Line II instead, the UL 857-listed family Schneider actually sells domestically.
Canalis is six ranges by amperage and application: KN for lighting/small power up to 160 A, KS for power distribution at 100-1,000 A, KT for high-power distribution at 1,000-5,000 A, KR as a cast-resin IP68 harsh-environment version of KT at 800-6,300 A, and the lighting-only KBA/KBB pair at 25-40 A. Fixed tap-off pitch (500 mm on one KS accessory) distinguishes it from Starline-style continuous-slot track busway.
Two confusion traps sit next to Canalis in Schneider's own catalogue. A separate IEC-rated product is branded "I-Line II" (630-6,300 A, IEC 61439-6, Square D architecture) rather than Canalis, with no documented tap-off compatibility between the two families. "iBusway for Data Center" is a third, discontinued, US-market Galaxy-family product (100/225/400 A, UL 857) that shares no lineage with Canalis despite the overlapping name.
Schneider publishes no UL 857 or CSA listing for Canalis in any of its catalogues, so there is no UL-versus-IEC rating gap of the kind Vertiv's PowerBar Track shows (2,000 A UL against 2,500 A IEC). Canalis carries IEC-basis short-circuit figures only: 40-90 kA Icw on KT and up to 100 kA on KR.
Why it matters
Getting this wrong is a credibility problem, not a technicality: Schneider's own FAQ says Canalis cannot be bought in the US or Canada, so treating it as a domestic product misleads a North American buyer before pricing even enters the conversation. The two adjacent products sharing Schneider's name space, IEC-branded "I-Line II" and the discontinued "iBusway for Data Center," make the wrong-product risk concrete rather than theoretical for anyone searching "Schneider busway."
Who buys it
International and gray-market equipment buyers and integrators working outside North America, where Canalis is Schneider's actual local busbar trunking product for industrial, commercial, and data center distribution. US and Canadian buyers researching Schneider-branded busway for domestic procurement, who need redirecting to Square D I-Line/I-Line II before sourcing begins. Buyers assembling cross-border or export deals who need the Canalis-versus-I-Line distinction settled before a purchase order goes out.
Role in the data center
Canalis KR's own brochure names data centers explicitly among its target sectors, describing the range as fire-resistant with high-uptime requirements, alongside oil and gas, marine, and solar-farm deployments. This applies to IEC-market data centers only: a North American data center buyer cannot procure Canalis at all, and should look to Square D I-Line/I-Line II for the equivalent role in a US or Canadian facility.

Major variations
Canalis spans six ranges by amperage and application: KN for lighting/small power at 160 A and below, KS for power distribution at 100-1,000 A, KT for high-power distribution at 1,000-4,000 A aluminum (KTA) or 1,000-5,000 A copper (KTC), KR as a cast-resin IP68 harsh-environment version of KT at 800-5,000 A aluminum (KRA) or 1,000-6,300 A copper (KRC), and the lighting-only KBA/KBB pair at 25-40 A. A separate Schneider product is also IEC-rated but carries the "I-Line II" brand rather than Canalis: a "Catalogue IEC I-LINE II busway" document covers 630-6,300 A built on Square D architecture rather than the Telemecanique-heritage Canalis design, and Schneider documents no tap-off or housing compatibility between the two families. Schneider also marketed "iBusway for Data Center," a discontinued US-market product under the separate Galaxy brand that shares no lineage with Canalis.
Compatibility and dependencies
RS Online's listing for KTA2500ED4403, a 2,500 A aluminum Canalis KT busbar section, documents it as "compatible with Canalis KS and KT plug-in units" - a direct, sourced cross-range tap-off compatibility statement, the Canalis analog to Schneider's published PBQ 400-600 A fusible-switch compatibility across I-Line and I-Line II. This specific pairing is not confirmed universal across every Canalis SKU: Schneider publishes no broader statement covering every KS/KT/KR/KN combination, so verify fit by exact part number rather than assuming range-wide interchangeability. Individual tap-off units can also carry a narrower voltage ceiling than the busway run they mount to - the KSA630ET43A tap-off datasheet rates operation at 230-690 V, below the 1,000 V insulation rating published for the KT/KS busway housings themselves.

Trend: stable
Lifecycle and maintenance
Schneider publishes no Canalis design-life figure in years, and no major busway OEM publishes one for its own product either. The current Canalis KT installation guide (document QGH3492101, dated 2026-01-13) addresses joint installation and tap-off mounting but states no fixed overhaul interval. Canalis is unpowered distribution hardware with no embedded controls or firmware, so controls support, a question that matters for UPS or generator equipment, does not apply to this product class.
Thermal and emissions profile
Canalis uses no refrigerant, so refrigerant GWP and the EPA phase-down timeline do not apply to this equipment class. The comparable cross-standard question for busway is UL-versus-IEC short-circuit withstand, and Canalis is the negative case: it carries no UL 857 or CSA listing in published sources as of August 2026, so there is no UL figure to set against its IEC ratings the way Vertiv's PowerBar Track shows 2,000 A UL against 2,500 A IEC on one physical product. Canalis publishes only the IEC-basis number, 40-90 kA (Icw, 1s) across the KT range and up to 100 kA on the cast-resin KR range, with no UL-basis figure existing to compare it against.
Common failure points
- Bolted/plug-in joint — Localized hot spot on thermal scan; discoloration or bluing at the joint face
- Seal/gasket, IP68 KR range — Moisture ingress inside the housing; visible corrosion on aluminum conductors
- Tap-off/plug-in unit contact — Loose insertion; arcing marks; inability to fully seat the plug-in unit
- Conductor identity mismatch — Amperage rating or measured weight inconsistent with the nameplate model code
- Insulation degradation — Reduced megger reading between conductor and housing
- Fire-barrier insulation, KBA/KBB ribbon conductor — Scorching or embrittlement of the ribbon-cable insulation beyond normal service wear
- Standards-marking mismatch — UL or CSA marking present on a section sold or labeled as Canalis
Inspection checklist
Nameplate rated current: confirm the exact SKU (e.g., KTA2500, KSA630) matches the physical section: Canalis current steps are non-linear (1,000/1,200/1,600/2,000/2,500/3,000/4,000 A on KTA) so a mismatched or re-stamped nameplate is easy to overlook. Short-time withstand current (Icw): verify against the OEM table by SKU, not the range headline figure: KSA630 carries 32.1 kA/1s and 67.5 kA peak specifically, a figure that does not apply to every KSA rating. IP rating and seal integrity: KT sections are rated IP55 indoor, KR sections IP68 outdoor/severe: inspect gaskets, end-caps, and cable-entry glands for degradation, since a compromised seal drops effective protection below the nameplate figure on a used section.
Regional notes
Canalis is not available for sale in the US or Canada per Schneider's own support FAQ, last modified 2024-05-14. Used and new-old-stock Canalis circulates through UK, Malaysian, Philippine, EU and Australian channels; every published Canalis price sits in one of those regions, and Canalis does not appear in US dealer, distributor or listing-service inventory.
