SPD application in conjunction with Class II equipment

In addition to CLC/TS 61643-12, this Technical Report describes the principle of erecting SPDs to be connected to 50 Hz a.c. power circuits, rated up to 1 000 V r.m.s. in conjunction with Class II equipments. In addition to EN 61643-11, this Technical Report gives specific guidance for SPDs intended to be installed in class II equipments.

SPD Anwendungen in Verbindung mit Schutzklasse II

Parafoudres destinés à être utilisés avec des équipements classe II

Uporaba SPD v povezavi z opremo razreda II

Poleg standarda EN 61643-12 to tehnično poročilo opisuje način postavljanja prenapetostnih zaščitnih naprav (SPD) za priključitev na električne tokokroge z napetostjo 50 Hz pri izmeničnem toku z nazivno vrednostjo do 1000 V efektivne izmenične napetosti v povezavi z opremo razreda II. Poleg standarda EN 61643-11 to tehnično poročilo obravnava specifične smernice za prenapetostne zaščitne naprave, namenjene za vgradnjo v opremo razreda II.
