ABSTRACT:
A modular current transformer containing both air and metal cores on a common load strap provides sensing current to the electronic trip unit within the circuit interrupter along with supplying operating power to the trip unit components. The current sensing coil is arranged concentricity within the transformer core while the power generating coil is arranged concentricity outside the core.
