Product details
| General | |
| Note | Depending on the voltage Uc, the installation height, and the pollution degree, additional minimum lateral distances to grounded, conductive surfaces may need to be observed. Pollution degree 2: Uc ≤440: No lateral distances required. Uc >440 V ... 880 V: A minimum distance of 6 mm must be observed up to an installation height of 3000 m. Pollution degree 3: Uc ≤385 V: For wiring using a fork-type cable lug, an additional minimum distance of 1 mm must be observed for cross-sections ≥16 mm². Uc >385 V ... 440 V: See the table in the download area under the item Packing slip in the installation notes. |
