  • Patent number: 9633756
    Abstract: An arrangement for connecting a circuit breaker in a circuit, for example, in a switchgear, having conductors designed in the form of busbars and supported against each other for receiving forces resulting from normal operating behavior and from short circuit situations. The conductors are disposed in at least two-part claddings each completely peripherally enclosing the respective conductor and serving as electrical insulation.
    Type: Grant
    Filed: May 9, 2013
    Date of Patent: April 25, 2017
    Assignee: ABB AG
    Inventor: Ralf Graf
  • Patent number: 8994543
    Abstract: A diagnosis and maintenance device is provided for a switchgear assembly, for example, a low-voltage switchgear assembly. The diagnosis and maintenance device includes a data processing device and at least one first, internal interface device, which is connected to at least one connected and communication-capable apparatus in the switchgear assembly in a communicating manner and polls and/or processes the diagnosis and maintenance information and/or status information of the connected and communication-capable apparatus and provides said information in an accessible manner as usable and/or human-readable information and/or outputs and/or displays said information as usable and/or human-readable information. A switchgear assembly having such a device is also provided.
