PITTSBURGH … Diversified industrial manufacturer Eaton Corporation today announced it will include the Series NRX^™ Low Voltage Power Circuit Breaker as an option with Magnum DS^™ Low Voltage Metal-Enclosed Switchgear. This innovation promotes sustainability by reducing the overall footprint up to 45 percent compared to standard switchgear layouts.

Key advantages of Series NRX Breakers used in combination with Magnum DS

Switchgear include extended contact life through improved fault interruption and open circuit isolation technology, electronic trip innovation including Arc Flash Reduction Maintenance System and breaker-cell mounted communication modules. The NRX Breaker’s compact size can also accommodate up to eight 800A frame breakers in a 24” wide structure in traditional American National Standards Institute (ANSI)/Underwriters Laboratories (UL) 1558 switchgear; and the breaker can protect up to 65K at 480 VAC with SWGR bus bracing at 100kA standard.

“Series NRX breakers are just one example of Eaton’s ability to develop leading-edge technology that promotes sustainability,” said Bill VanLandingham, vice president and general manager, Eaton’s Electrical Group Power Distribution Control and Assemblies Division. “The Series NRX Breaker’s high interrupting, small size, reduced weight, broad trip-unit capabilities and ergonomic design make this innovative product ideal for applications in which floor space is at a premium.”

When Series NRX Breakers are included in Magnum DS Switchgear solutions, the resulting systems will continue to meet key industry standards, including ANSI C37.20.1, ANSI C37.51, UL1558/UL1066, UL891/UL489, CSA-C22.2 No.31-M89 and Seismic (IBC 2006 and

CBC 2007).

The resilience of Series NRX Breakers has been tested to 20,000 mechanical operations and 10,000 electrical operations, significantly exceeding the requirements of UL, and Independent Electrical Contractors (IEC) standards.

Eaton understands that arc flash safety is tremendously important to a wide range of industries who strive to protect what they value most – their people. In April of 2008, Eaton made a $500,000 contribution to the Institute of Electrical and Electronic Engineers (IEEE) and the National Fire Protection Association (NFPA) Arc Flash Phenomena Collaborative Research Project. As a platinum level sponsor of this important initiative, Eaton supports efforts to improve electrical safety standards, predict the hazards associated with arcing faults and accompanying arc blasts, and provide safeguards for employees.
