  • Patent number: 9431199
    Abstract: A circuit breaker including two contacts, a pressurization chamber, a nozzle arrangement designed to blow an arc in a quenching region, with a narrowest passage of a pressurization chamber outflow channel to be passed by outflowing quenching gas defining a pressurization chamber outflow limiting area, a narrowest passage of a nozzle channel to be passed by outflowing quenching gas defining a nozzle outflow limiting area, the smaller area of which defining an absolute outflow limiting area, with quenching gas having a global warming potential lower than the one of SF6 over an interval of 100 years; wherein a ratio of the pressurization chamber outflow limiting area to the nozzle outflow limiting area is less than 1.1:1.
    Type: Grant
