September 4, 2012 – GE says its Evolution Series switchboard, officially unveiled at NECA 2012, accommodates “the latest technology for people and property protection”, such as Instantaneous Zone Selective Interlocking (I-ZSI) and Reduced Energy Let Through (RELT). I-ZSI simultaneously provides arc fault protection and instantaneous selectivity, which GE claims is an industry first. Meantime, RELT Instantaneous trip allows a circuit breaker to be temporarily set to a more sensitive pickup to provide better protection during installation and maintenance, promising an added margin of safety for personnel. The switchboards are suitable for applications ranging from healthcare and data centres to stadiums and casinos. The design of the front neutral space in the series provides the clearance to accommodate additional breakers in a more efficient footprint, says the company, adding that the Evolution Series provides expanded coverage for nearly every switchboard application: 6000A rating, 667A/si. bus density, and 4000A 100% rated stationary.
