Abstract

The invention relates to a triggered fuse for low-voltage applications for protecting devices that can be connected to a power supply system, in particular surge protection devices, consisting of at least one fusible conductor which is located between two contacts and is arranged in a housing, and also consisting of a trigger device for controlled disconnection of the fusible conductor in the event of malfunctions or overload states of the respective connected device, wherein an arc quenching medium is introduced into the housing. The at least one fusible conductor has a plurality of conventional electrical bottlenecks, which are designed for the rated load of the respective fuse. At least one further additional geometric bottleneck is provided, which is disconnectable by rupturing depending on the trigger unit when applied by tension.
