ABSTRACT:
An electronic sectionalizer includes mounting structure including first and second electrical contacts spaced from one another and electrically conductive structure having an external surface and provided with first and second electrical terminals adapted to engage the first and second electrical contacts of the mounting structure in a closed condition of thesectionalizer. The sectionalizer provides for the release of the electrically conductive structure from engagement with at least the first electrical contact to permit the electrically conductive structure to move from the closed position to an open position, and an actuator is provided for actuating the release. A detector is provided to detect a predetermined condition in the sectionalizier and the actuator is controlled in response to the detection by an electronic control circuit mounted to the external surface of the conductor.
