摘要： A low-voltage power switch having a switching chamber with a switching contact arrangement and an arc extinguishing device. Sealing of the switching chamber is achieved by an apron-like projection on the movable contact support in combination with a stationary curved recess and by ribs opposite the movable contact support and a sealing arrangement on the stationary counter-contact.

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： An arc chute for a circuit-breaker has a chute member with arc splitters and an end member that seals off the chute member to the top. The end member has three barriers for arc gases, the first and the second barrier have webs with a more or less square cross-sectional shape which are arranged in double the pitch of the arc splitters. Situated above the second barrier is a cooling chamber, which is sealed off to the outside by the third barrier that is provided with outlet orifices.

摘要： A switch with a selective release having a stroke armature activated by an electromagnet in response to a release current to actuate a switch latch. A lever arrangement encloses a stroke armature in such a fashion that it can be swiveled by the stroke armature from a rest position into a position in which the stroke armature may be rapidly moved to impact on the latch.

摘要： A power switch has a pole unit with a switch contact arrangement, an arc quenching device and a flow channel. Switching gases from the arc quenching device are provided into the flow channel and, after cooling, provided to the side of the switch contact arrangement away from the arc quenching device. The entire gas chamber of the power switch is essentially sealed. The flow channel may include a valve flap and a deionising device.

摘要： A contact assembly is provided for current-limiting low-voltage circuit breakers. The contact assembly has a two-armed contact lever swivel-mounted on a central bearing pin whose lever arms are equipped at their ends with contact pieces. The contact lever is equipped with a slot for mounting on the bearing pin whose longitudinal axis extends approximately at a right angle to the longitudinal axis of contact lever. The contact lever has a stop extending at approximately a right angle to its longitudinal axis for a catch swivel-mounted on the bearing pin. The contact forces on both lever arms cannot be influenced by the swivel mount or by the drive mechanism of the contact lever, but are determined exclusively by the biasing springs.
