January 28, 2010 — A white paper from Rockwell Automation highlights the inherent dangers of arc flash, discusses the standards guiding arc-flash safety, and details the role that arc-resistant motor control centers (MCCs) play in helping to contain arc energy and reduce hazards. “Advances in Low Voltage MCC Technology Help Reduce Arc-Flash Hazards and Minimize Risks” discusses how changing industry standards are putting more focus on arc-flash risks, and highlights the key features and components of an effective arc-resistant MCC design. The paper stresses the importance of understanding the performance criteria that must be met before an MCC can be classified as an arc-resistant design.
According to the paper, an arc-resistant MCC is designed and built to provide a complete structural solution in accordance with defined industry standards. Arc-resistant equipment is designed to minimize arc-flash exposure by extinguishing the arc, controlling the spread of the arc or channeling the arc pressure and energy away from personnel. “As new codes and standards continue to raise the awareness of arc-flash hazards, users are looking for leading-edge products capable of delivering higher levels of safety,” said John Kuroski, product manager, Low Voltage Motor Control Centers, Rockwell Automation.
“Arc-resistant MCCs are helping to fulfill this need with improved safety features designed to help shield personnel from the effects of an internal arcing and minimize the need to enter an arc-flash boundary zone.” Rockwell Automation, Inc.
