| Zusammenfassung: | The invention represents a switching cartridge, which is filled with insulating gas, for cutting off an excess current automatically. It operates on the principle of a compression circuit breaker with its own pressure generation, and, in addition to the arc extinguishing device, contains a spring-force accumulator and an integrated primary trip device with ball notches. As a result of the compact construction, it is particularly suitable for installation in encapsulated medium-voltage switchpanels which are filled with insulating gas, preferably for substations. |
