Abstract

A circuit breaker having manual control, an over-center contact mechanism, and a magnetic sensing coil, wherein the over-center contact mechanism is disposed between the manual control and sensing oil. 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.
