Closing

In the open position the contacts are kept open by the force of the opening springs. To close 
the contacts the coils of the magnetic actuators are excited by a current impulse from the close 
capacitors of the CM. The opening springs are compressed when the contacts close. In the closed 
position the contacts are kept closed only by means of the magnetic force. The ISM maintains the 
closed position without mechanical latching even in the event of a failure of the auxiliary power 
supply (Figure 5).

Opening

To open the contacts a current impulse in the reverse polarity derived from the opening capacitors 
of the CM is injected in the coils of the magnetic actuators, releasing the magnetic holding force. 
The compressed opening springs and contact pressure springs open the contacts (Figure 5). 

Manual-Emergency-Tripping

The ISM can also be manually opened. When the synchronizing shaft is rotated, a force exceeding 
the magnetic attraction forces of the ring magnet is applied to the armature, which subseqently 
starts to move. As the air gap increases, the opening springs and the contact pressure springs 
overcome the magnetic holding force, and the vacuum interrupter opens.

Manual Closing

The ISM can only be closed electrically via the CM. In the case of a failure of auxiliary power 
supply the contacts can be closed using an alternative auxiliary power supply such as a battery. 
Mechanical closing is not possible and leads to the destruction of the ISM.
