About this item

The load and motor switch of type 8544/1 is an explosion-protected
electrical device in a flameproof enclosure. It is used for the
separation or activation of electrical circuits in hazardous areas of
Zone 1, Zone 2 or in the safe area.
The load and motor switch 8544/1 is available in versions
8544/1-3. (3 poles) and 8544/1-4. (3 poles + N).
The switches are actuated by means of an actuator insert which
is connected to the switch by means of a selector shaft.
Up to two certified contact elements of the type 8080/1 can be
mounted at the load and motor switch 8544/1.
The switching function of the contact elements is defined by the
