Caneco BT can’t find any circuit-breakers for calculation of a 690V IT installation
Catégorie FAQ:
Catalogues de matériels électriques
In this voltage range, the neutral system is most commonly chosen.
With an IT installation, you need to check the breaking capacity on one pole of the protection. The manufacturers don’t usually provide data for voltages above 415V. In this particular case, you can forcibly select an off-catalogue circuit-breaker and then you’ll need to approach the manufacturer directly to confirm or otherwise your choice.
