Patent number: 10020152Abstract: A plug-on neutral circuit breaker includes a housing, a neutral terminal, and a biasing member. The neutral terminal is pivotally coupled to the housing and includes a body portion, a first leg, and a second leg. The first leg extends from the body portion in a first direction and the second leg extends from the body portion in a second direction. The biasing member is positioned within the housing and is configured to engage the second leg of the neutral terminal, thereby biasing the neutral terminal in a first rotational direction. The biasing of the neutral terminal in the first rotational direction causes a portion of the first leg of the neutral terminal to be urged into contact with a neutral bar of an electrical distribution apparatus in response to the plug-on neutral circuit breaker being installed in the electrical distribution apparatus.Type: GrantFiled: June 27, 2013Date of Patent: July 10, 2018Assignee: Schneider Electric USA, Inc.Inventors: David R. Pearson, Jason Potratz

Patent number: 9548548Abstract: A method of assembling a load center featuring a dielectric barrier that securely retains a plug-on neutral rail without requiring any fasteners. The dielectric barrier and the rail are installed in the same Z-axis direction, which is orthogonal to a rear wall of an enclosure into which the load center is installed. Retention features in the dielectric barrier can create a snap-fit connection between the rail and the barrier, or the barrier can feature a support feature onto which the rail snaps as the rail is installed relative to the dielectric barrier in the Z-axis direction. The snap fit connections eliminate the need for any fasteners, and together with the Z-axis assembly, the assembly process is simplified and accelerated and the possibility of assembly error is reduced or eliminated.Type: GrantFiled: December 19, 2012Date of Patent: January 17, 2017Assignee: Schneider Electric USA, Inc.Inventors: Jason D. Potratz, David R. Pearson, Kim D. Wheeler, William J. Broghammer

Patent number: 8929055Abstract: A plug-on load center featuring snap-in or snap-on neutral rails that are retained securely in the load center on or between a dielectric barrier without requiring any fasteners and assembled by installing the dielectric components and neutral rail along the same direction orthogonal to a rear wall of an enclosure that houses the load center. The snap-in configurations feature dielectric barriers with fingers that create a snap-fit connection between the neutral rail and a shield member. The neutral rail is forced between the fingers, which separate and then snap back to their original position once the neutral rail is fully seated in the dielectric barrier. The snap-on configurations feature a neutral rail that is snapped onto the dielectric barrier and retained in the load without any fasteners. The barrier can include retention members that snap-fit into corresponding features of the neutral rail when it is installed onto the barrier.Type: GrantFiled: December 19, 2012Date of Patent: January 6, 2015Assignee: Schneider Electric USA, Inc.Inventors: Jason D.

Patent number: 8735759Abstract: A debris collection slot or groove formed near the exit of a vent channel in a circuit breaker. Debris is produced during a circuit interruption, causing the debris to travel into the vent channel toward an opening where it exits the circuit breaker. Too much accumulated debris can lead to a ground strike or a cross-phase condition. The debris collection groove, formed near the exit opening of the vent channel, has no significant effect on the internal pressure generated during the circuit interruption. Multiple grooves can be formed near the exit opening for trapping more debris. When the vent channel is bent, the grooves are positioned on the outer curve of the last bend of the vent channel to trap the higher-density debris traveling around the curve.Type: GrantFiled: November 3, 2009Date of Patent: May 27, 2014Assignee: Schneider Electric USA, Inc.Inventors: Jason Potratz, David R.

Patent number: 7176771Abstract: An improved filter assembly for a circuit breaker includes a generally rectilinear filter housing having at least two filter mounting zones for receiving at least two filter assemblies, so as to define, in the aggregate, a filter assembly, and at least two filter assemblies configured for interfitting with the filter mounting zones of the filter housing, each filter assembly comprising a generally rectilinear filter body having a given peripheral configuration and a filter gasket configured for interfitting about a periphery of the filter body for sealingly engaging the filter body relative to the filter housing in response to forces encountered by the filter assembly both upon assembly and in operation. The filter assembly may further have a small hole diffuser having a peripheral configuration similar to the peripheral configuration of the filter bodies, in the aggregate, when assembled with the filter housing and configured for interfitting within the filter housing.Type: GrantFiled: August 24, 2001Date of Patent: February 13, 2007Assignee: Square D CompanyInventors: Timothy R.
