| Zusammenfassung: | An electrical circuit-breaker (10) with insulating casing (12) encloses a main arc-extinction chamber (26), and a decompression chamber (40) communicating with the outer environment through an exhaust orifice (42). According to the invention, the exhaust orifice (42) is accommodated in the rear face (18) of the insulating casing (12) in order to divert the ionised gas flow from the fixing base (20) side towards a region devoid of connection leads or live conductive parts. |
