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.
