Abstract
The load lugs electrically connecting circuit breakers employing electronic trip units with associated electrical distribution circuits are shaped to provide magnetic flux concentration to Hall effect current sensors within the electronic trip unit circuit. The Hall effect sensor is positioned within the shaped region of the load lug for optimum focus of the magnetic flux within each phase of a multi-phase electrical distribution system.
