Claims (3)

Patent-Ansprüche:Patent Claims: 1. Sicherungsanordnung, bei der einer geschlossenen kurzschlußsicheren Patronensicherung eine schwächere Vorsicherung vorgeschaltet ist, dadurch gekennzeichnet, daß das Schmelzmaterial der Vorsicherung aus Zinn oder einem ähnlichen Metall von niederem Schmelzpunkt besteht.1. Fuse arrangement with a closed, short-circuit-proof cartridge fuse a weaker backup fuse is connected upstream, characterized in that the fuse material of the backup fuse consists of tin or a similar metal with a low melting point. 2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Vorsicherung einen so großen Querschnitt erhält, daß sie bei Kurzschluß sich langsamer erwärmt als die Hauptsicherung, so daß die letztere früher abschmilzt als die Vorsicherung.2. Arrangement according to claim 1, characterized in that the backup fuse a receives such a large cross-section that it heats up more slowly than the Main fuse, so that the latter melts off earlier than the backup fuse. 3. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Vorsicherung mit einer besseren Wärmeisolation versehen wird als die Hauptsicherung.3. Arrangement according to claim 1, characterized in that the backup fuse with better thermal insulation than the main fuse.
