M Series

The M Series made of die-cast aluminium is a cost-effective alternative to the E Series. With 3 contacts it is suitable for many applications. Thanks to the large inspection glass, the oil level can also be visually monitored very easily, and the adjustment of the individual switching points is made much easier.
