Die Schutzgeräte der WI Line
- Alle Schutzgeräte dieser Produktlinie von SEG Electronics sind wandlerstromversorgt, d. h. sie entnehmen ihre Energie aus den Stromwandlern.
- Da sie keine Hilfsstromquelle benötigen, eignen sich die Schutzgeräte der Produktlinie WI gut für den Einsatz in unabhängigen Übertragungs- und Verteilungsanlagen, lokalen Netzen und Lastschaltanlagen (Ring Main Units).
- Die Auslösecharakteristiken reichen von zweistufigem, unabhängigem (DEFT) und abhängigem (INV) Überstromzeitschutz bis hin zu speziellen Kennlinien. Als weitere Optionen bieten wir einige Relais mit integriertem Erdschlussschutz.
- SEG Electronics hat Serienprodukte entwickelt, die zu fast jedem auf dem Markt gängigen Leistungsschalter passen. Die elektronischen Teile der Relais sind komplett versiegelt. Dadurch sind die Relais auch vor den rauhesten Umwelteinflüssen geschützt.
- Eine ANSI-Übersicht zu wandlerstromversorgten Schutzgeräten enthält diese PDF-Vergleichstabelle.
