| Introduction | Data sheets | Operating Instructions | Certificates |
The load and motor switch 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 the 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 to the load and motor switch 8544/1
The switching function of the contact elements is defined by the contact version and their position in the load and motor switch (left-hand: delayed (ON), advanced (OFF); right-hand: synchronising).
