Lower total system cost with QuiXtra

How is this achieved? Installing an upstream device that limits the prospective short-circuit values will enable the user to utilize downstream devices with lower breaking capacities. GE’s breaker features, such as Back-Up Protection, Selectivity Plus and ArcWatch, allow coordination between devices and excellent breaking capacity at a lower cost.
