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.
Claims18
A circuit breaker comprising 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.
A circuit breaker comprising a collapsible toggle linkage for selectively applying a force along an axis, and a solenoid, wherein said axis generally intersects said solenoid.
A circuit breaker, comprising collapsible toggle linkage, a contact bar having an open circuit position and a close circuit position, and a magnetic current sensing coil, wherein said contact bar is disposed between said collapsible toggle linkage and said magnetic current sensing coil.
A circuit breaker having a housing comprising a contact mechanism having a contact bar rotational axis, an external manual interface extending through a front surface of the housing, a first pair of walls intersecting said axis, and a second pair of side walls not intersecting said axis, wherein a magnetic sensing coil of said circuit breaker is not disposed between the contact mechanism and the second set of side walls.
