Abstract

Die Erfindung betrifft elektrische Schalter, insbesondere Leitungsschutzschalter oder Motorschutzschalter, mit wenigsten einer Kontaktstelle, an der bei einer Schalthandlung ein Lichtbogen entsteht. Mit einem aus mehreren Löschblechen (11) gebildeten Lichtbogenlöschblechpaket (10), dessen Löschbleche mittels Halteelementen (26,27,40,41,76,77,104,105,164,165) auf Abstand zusammengehalten sind, sind die Halteelemente aus einem Thermoplast hergestellt, deren Nachmontage strahlenvernetzt ist.

The invention relates to electrical switches, in particular circuit breaker or motor protection switch, with at least one contact point at which an arc occurs during a switching operation. With an arc quenching plate package (10) formed from a plurality of quenching plates (11), the quenching plates of which are held together at a distance by means of holding elements (26, 27, 40, 41, 76, 77, 104, 105, 164, 166), the holding elements are made of a thermoplastic whose post-assembly is radiation-crosslinked.
