power dissipation of the article:
The power dissipation at a typical load of 80 % results to 9.0 W.
(The power dissipation at full load would be 14.1 W.)
| Supplementary data IEC | |
|
The following values have been verified with tests under certain conditions. Please ask Wöhner for this conditions before designing your panel. |
| max. permitted voltage (IEC) AC: | 725 V |
| max. permitted voltage (IEC) DC: | 800 V |
| A fuse-combination unit acc. to IEC 60947-3 can only be operated at a higher voltage than its rated voltage, if it is used as a fuse-disconnector without breaking capacity, up to its max. rated insulation voltage and labelled as such. |
| Entsprechend den angegeben AC- und DC- Schalteigenschaften und unter Berücksichtigung der Überlastbedingungen, sind gewisse Abstände zu geerdeten Metallteilen einzuhalten. Nähere Informationen auf Anfrage. Bei Verwendung als Trennschalter ist die Einhaltung der Abstände nicht erforderlich. |
