Abstract
A circuit interrupting device includes a grounded neutral transformer core, a high frequency transformer core, and a differential transformer core nested within the grounded neutral transformer core and/or the high frequency transformer core. The grounded neutral transformer core and the high frequency transformer core are disposed in a stacked configuration with one another.
Claims22
A circuit interrupting device comprising:
- a core assembly defining a longitudinal axis and including:
- a grounded neutral transformer core;
- a high frequency transformer core, the grounded neutral transformer core and the high frequency transformer core are stacked along the longitudinal axis;
- and
- a differential transformer core disposed within both the grounded neutral transformer core and the high frequency transformer core.

A method of manufacturing a circuit interrupting device, comprising:
- stacking a grounded neutral transformer core of a core assembly and a high frequency transformer core of the core assembly along a longitudinal axis defined by the core assembly;
- and
- disposing a differential transformer core of the core assembly at least partially within both the grounded neutral transformer core and the high frequency transformer core.
A circuit interrupting device, comprising:
- a core assembly defining a longitudinal axis and including:
- a grounded neutral transformer core;
- a high frequency transformer core in direct abutting engagement with the grounded neutral transformer core, such that the high frequency transformer core and the grounded neutral transformer core are stacked along the longitudinal axis;
- and
- a differential transformer core concentrically disposed within both the grounded neutral transformer core and the high frequency transformer core.
