    摘要: A multipole low-voltage circuit breaker with an insulating material housing and arc quenching chambers. By a new mechanical design, the installation of the arc quenching devices is to be facilitated. All arc quenching chambers of a switchgear are arranged in a quenching chamber housing which is subdivided by partitions and is fastened to the insulating material housing of a circuit breaker. The quenching baffles are fastened directly to the walls of the arc quenching chambers. A low-voltage circuit breaker with an insulating material housing of compact design is thus provided.

    摘要: A contact arrangement of a low-voltage circuit breakeer with electrodynamic breaking or opening. In contact arrangements which contain a compression spring for pretensioning a contact lever into the make position or after a dead center position is passed, the assembly is to be simplified and the use of an assembly fixture is to be made unnecessary. The pivot bearing of a contact lever at a contact lever carrier is formed by a pan-like depression of the contact lever carrier as well as an extension of the contact lever engaging the depression. Furthermore, a stop surface for the open position of the contact lever is arranged at the contact lever carrier. A brief application of force is sufficient for connecting the contact lever to the contact lever carrier. A current-limiting low-voltage circuit breaker of compact design is thus provided.

    摘要: A current overload tripping device having a time-delayed leading tripping action during uneven loading of the phases of a multiphase circuit. The tripping device includes a current pickup for each phase wherein the current pickup members are connected in series with one another and with an electromagnetic converter. Each of the current pickup members comprises a winding surrounding a magnet yoke of an electromagnetic tripping device of each phase and the electromagnetic converter comprises a temperature/time-dependent device operating to provide a time-delayed tripping signal.
