Abstract:
Electrical device contact assemblies with separable electrical contacts exhibiting enhanced arcing constriction are disclosed. Electrical device contact assembly includes first and second electrical contacts separable along a separation path, and a magnetic field generator configured as part of a line conductor that is operable to produce a magnetic field that acts on the separation path during a short circuit event. Electrical devices including the electrical device contact assembly and methods of operating the electrical device contact assembly are provided, as are other aspects.
