Abstract
An sensor for sensing electrical current flowing in a conductor includes a housing for retaining a toroidal core formed of a ferric material and having a slot defining an air gap, and a Hall Effect sensor integrated circuit chip positioned in the air gap for sensing electrical current flowing in a conductor received in a central aperture of the core. The central aperture is defined by an annular portion of the housing formed by inner and outer walls joined by a floor and retaining the core. A tab in the annular portion extends into the core slot to limit movement of the core and protect the integrated circuit chip.
