ABSTRACT:
A circuit breaker having a manual control, an over-center contact mechanism, and a magnetic current sensing coil, wherein said an over-center contact mechanism is disposed between said external manual control and said sensing coil. For example, a collapsible toggle linkage selectively applies a force along an axis, which generally intersects the coil. The circuit breaker has a housing for a contact mechanism having a contact bar rotational axis. The magnetic sensing coil of the circuit breaker is not disposed between the contact mechanism and a side wall of the housing.
