Product overview
Nu1 is Nuventura’s metal-enclosed primary-distribution GIS platform using pure industrial dry air as the insulating gas and vacuum technology for interruption. The verified range covers 24 kV and 36 kV single-busbar variants.
Current released configuration
The current released feeder rating is 1,250 A. Nuventura’s online technical table also shows a 2,000 A feeder option; that value belongs to Phase 2 and is not presented here as a currently released product rating. The separate 2,500 A figure is the rated busbar current and must not be used as the feeder rating. Published short-time withstand is 31.5 kA for 3 seconds, with 50/60 Hz operation.
Source discrepancy
The manufacturer’s current web table lists both 1,250 A and 2,000 A without displaying the commercial phase beside the values. LearnSwitchgear therefore records 1,250 A in the structured rated-current field and treats 2,000 A as Phase 2 until current supply documentation explicitly confirms release.
Engineering significance
Nu1 is relevant to primary-distribution projects seeking to remove fluorinated insulation gases while retaining a compact GIS architecture. Nuventura describes its 36 kV design as a product first; LearnSwitchgear records that wording as a manufacturer claim, not an independently certified market ranking.
Specification caution
Confirm the exact panel arrangement, internal-arc classification, cable interface, regional certification and current Lucy Electric/Nuventura supply documentation for the project.
