3. Other advantages

After disengagement, the handle is located in the middle position (MS132,MS165,MO132, MO165,MS132-T).

When a short-circuit trip occurs, the fault (MS132,MS165,MS132-T) can be clearly and reliably indicated in a separate window.

The handle can be in the off position with standard lock lock directly, without accessories (MS132, MS165, MO132, MO165 MS132 - T)

It matches perfectly with ABB contactors
