Patent number: 9443689Abstract: The invention relates to a fuse for connection to a protective component of an overvoltage protective device. A fuse wire runs between a first cap and a second cap. In some implementations, the fuse wire may be held on the first cap by means of a soldered connection and fastened to a connection electrode. The connection electrode may be movable with respect to a fuse body and under mechanical pretension with respect to a fuse body. The fuse wire melts when acted on with a high I2t, and the soldered connection melts upon external heating by the overvoltage protective device above a specified temperature by means of the thermal connection. Electrical contact between the first cap and the connection electrode is broken via the mechanical pretension if the fuse wire or the soldered connection melt.Type: GrantFiled: August 17, 2012Date of Patent: September 13, 2016Assignee: Phoenix Contact GmbH & Co.
