Patent number: 8334740Abstract: A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to be secured in generally close proximity to the stationary contact. During communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with the stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. A pair of arc guides extend along the magnetic intensifier and, cooperatively with the magnetic force, ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor. Such a construction increases the operable range and lifecycle of the contactor by reducing the damage associated with propagation of the circuit termination arc.Type: GrantFiled: February 17, 2011Date of Patent: December 18, 2012Assignee: Rockwell Automation Technologies, Inc.Inventors: Jeffrey Ramsey Annis, Robert Alfred Duchrow, Theodore John Houck, III, James Peter Miller

Patent number: 7958623Abstract: A method of manufacturing a current switch magnetic intensifier that is constructed to be secured in generally close proximity to the stationary contact of the current switch. During termination of the communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with a stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. The intensifier is fitted proximate the stationary contact so that a pair of arc rails extend beyond the stationary contact such that a force of a magnetic field generated by the contactor magnetic intensified is directed in a common direction with a direction of reduced resistance of the pair of arc rails to ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor.Type: GrantFiled: December 18, 2008Date of Patent: June 14, 2011Assignee: Rockwell Automation Technologies, Inc.Inventors: Jeffrey Ramsey Annis, Robert Alfred Duchrow, Theodore John Houck, III, James Peter Miller

Patent number: 7723634Abstract: A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the contactor assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression.Type: GrantFiled: December 22, 2008Date of Patent: May 25, 2010Assignee: Rockwell Automation Technologies, Inc.Inventors: Jeffrey Ramsey Annis, Robert Alfred Duchrow, Susan L Beneke, legal representative, James Peter Miller
