Abstract: A network protector bus assembly, which is structured to be coupled to a roll-out circuit breaker having a plurality of quick disconnect assemblies, includes a line buss assembly and a load bus assembly. The line bus assembly has three elongated bus sub-assemblies, each with a stab extending generally perpendicular to the longitudinal axis of the line bus sub-assemblies. Each line bus sub-assembly stab has a width sufficient to accommodate at least two circuit breaker quick disconnect assemblies. Similarly, the load bus assembly has three elongated bus sub-assemblies, each with a stab extending generally perpendicular to the longitudinal axis of the load bus sub-assemblies. Again, each load bus sub-assembly stab has a width sufficient to accommodate at least two circuit breaker quick disconnect assemblies.

Abstract: A housing assembly for network protector fuses that includes a first and second C-shaped body and one or more cover plates. The first C-shaped body has a generally flat, rectangular front side and generally perpendicular first extension and second extension. The second C-shaped body has a generally flat, rectangular back side and generally perpendicular third extension and fourth. The first and second C-shaped bodies are coupled together forming an enclosure. The first body has one or more openings on the front side. The cover plates are coupled to the first C-shaped member and sealingly disposed over the openings in the first C-shaped body. The front side and the back side have a length sufficient to enclose more than one network protector fuse.

Abstract: A bus assembly for a network protector, where the network protector includes a housing, and where the bus assembly includes a plurality of busses having laminations and a rack assembly. The plurality of busses are mounted in the rack assembly and the rack assembly is coupled to the housing.

Abstract: A spring-biased electrical connector permits the connector to be moved into a retracted position for installation and removal of the components to which the connector is attached, and then extended to form an electrical connection with its mating connector. The spring-biased connector may be secured in electrical connection with its mating connector. Such a spring-biased connector is particularly useful for connecting a control relay to a network protector, although not limited to such use.

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.
