Current limited electrical devices, electrical device contact assemblies, and operational methods

摘要

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.
