Abstract:
A terminal shield for a circuit breaker, formed of an electrically insulating material, protects an operator from inadvertently touching the load terminal that would otherwise be exposed on the bottom side of the circuit breaker: In accordance with an example embodiment of the invention, the terminal shield is integrated with a toroidally shaped current transformer sensor, to enable measuring the current in a load wire that has been inserted through an aperture in the terminal shield. Preferably there is an access hole in the front portion of the terminal shield, which allows the operator to insert a tool through the front face of the circuit breaker, to tighten the load terminal onto the load wire. The terminal shield with the integrated current transformer sensor enables standardization of load current sensing capability for circuit breakers and further enables ease of installation without clutter in the confined regions of the load center.
