Abstract
A network protector system is provided in which the internal bussing of the network protector enclosure is constructed to adapt a four-pole circuit breaker for a three-pole network protection operation. This is provided by joining the central two bus conductors of the four line transformer input busses to make a single stab connection which interconnects with two central poles of the four-pole circuit breaker. The load output of the four-pole circuit breaker is interconnected with are overlapping stab which in turn is connected to a signal output bus bar so that the network protector system essentially converts a four-pole circuit breaker and line transformer system to a three-pole output system.
