  • the rotation of the closing hook 2 can be detected.
  • the closing shaft is rotated backwards to the original position and the closing hook 2 is following again, since it is driven by the closing spring forces towards the shaft.
  • This is again the normal state where the closing hook 2 is resting on the closing shaft 1 in the latched position.
  • the release of the losing hook is shown in the bottom right image, where the closing shaft 1 is rotated in the release direction, and the closing hook is released and the closing operation is started.
  • Fig. 5 shows an example of an additional eccentric element on the opening shaft 3.
  • an eccentric opening shaft 3 design is used in order to detect the functionality of the latching elements. Similar to the check on closing, as shown in the left image the opening latch is in a normal state with the opening hook 4 resting on the opening shaft 3 in the latched position. As shown in the right hand image, in the check state when the opening shaft 3 is rotated in an opposite direction to the normal release direction the opening hook 4 is rotated and checked for functioning in the latched position where the opening hook has been forced to undertake a small rotation. That motion can be detected with a sensor. Instead of using an additional sensor, the positive feedback or the actuating unit of the shaft (e.g. coil), that reached its end-position during the check state, can be used in order to detect the proper function of the latching elements.
  • the positive feedback or the actuating unit of the shaft e.g. coil
  • a sensor can be used to detect or monitor the force and/or torque required to perform the micromotion, and this can be evaluated against a normal, established, force and/or torque and this can be used to detect or establish the proper functioning of the latching elements.
  • Fig. 6 shows another design of the eccentric shaft. In this variant of the closing shaft, the eccentricity is introduced in a way, that a rotation of the shaft in the same direction as the usual operating direction is introducing the motion on the latching hook. The additional eccentric element 6 on the closing shaft is used to generate the necessary micromotion when the circuit breaker is in normal operating mode. In this case, a 2-step-actuation of the shaft is utilized. The working sequence is shown in Fig. 7 .
  • the closing hook 2 In normal state as shown in the top image the closing hook 2 is contacting the closing shaft 1, and is resting in its latched position. In check mode, as shown in the centre image the closing shaft 2 is rotated for a certain value (x degrees) with a special type of 2-step actuator and, by this, pushing and rotating the closing hook 2. For the release of the hook as shown in the bottom image the actuator rotates the closing shaft 1 for the additional value (y degrees) and the actautor can release the circuit breaker to open.
