Zusammenfassung:	A fault protection system for providing protection from fault current for components and devices on a lateral line proximate to a distribution transformer in a power distribution network. The system includes a single-phase recloser having a vacuum interrupter that is controlled by a controller. In one embodiment, the recloser has an insulating body that is molded in combination with an insulating body of a bushing that is connected to the distribution transformer. In this embodiment, the controller can be powered by a current transformer within the recloser. In another embodiment, the recloser is mounted to a utility pole separate from the distribution transformer, where the controller is powered by the low voltage side of the transformer and the current transformer is eliminated. An isolated power supply is provided between the transformer and the controller to provide voltage isolation.
