5.1.1.2. Electrical Characteristics
The part number of the G5 Stack Switchgear captures its product rating. The voltage rating is an
absolute maximum rating, and the current rating is a continuous rating (also referred to as the
'nominal' rating). Input power is internally regulated to be compliant with NEC class 2 requirements.
Part number format: NUVG5-SSG-<absolute-max-voltage>-<continuous-current-rating>-<fuse-rating>
The table below captures the absolute max rating for voltage and the continuous current rating for
current. For the fuse rating, please see
