Abstract
A circuit breaker mechanism has an armature component that is slidably displaceable between latched and tripping positions. The armature is connected to a moving contact carrier that is pivotally connected to an operating handle that is also pivotal. The armature is connected to the carrier by a spring. The armature has a latching formation which engages a projection. When tripped,the armature is slightly pivoted to clear the projection.
Claims19
A circuit breaker mechanism, which includes an operating handle, which is pivotal about a pivotal axis between on, off and tripped positions and which has an armature engaging portion;
- a moving contact carrier which is pivotally connected with the operating handle at a pivotal connection region that is spaced from the pivotal axis of the operating handle to be pivotal between on and off positions;
- an armature component that is substantially slidably displaceable between latched and tripped positions and has a reset portion engageable by the armature engaging portion of the operating handle, said armature component having a latching formation a fixed holding element that is engaged by the latching formation to hold the armature component in its latched position;
- and
- an urging means connected between the contact carrier and the armature component for displacing the armature component, the contact carrier and the operating handle.

- an armature component that is substantially slidably displaceable between latched and tripped positions and has a reset portion engageable by the armature engaging portion of the operating handle, said pivotal connection region of the contact carrier to the operating handle being located between the armature component and the pivotal axis of the operating handle;
- and
- an urging means connected between the contact carrier and the armature component for displacing the armature component, the contact carrier and the operating handle.

- and
- an urging means connected between the contact carrier and the armature component for displaceing the armature component, the contact carrier and the operating handle.
