Abstract
A circuit interrupter employing an electronic trip unit utilizes a current transformer assembly containing both air and metal cores on a common load strap for providing sensing current to the electronic trip unit along with supplying operating power to the trip unit electronic components. A two-part plastic housing provides support for the metal core and the sensing coil while further providing thermal transfer of heat generated within the transformer secondary windings out to the load strap.
