Holders without module
Holders made of plastic can only be attached to actuators and indicators made of plastic (3SU100) or plastic with metal front ring (3SU103).
Metal holders can be attached to all versions of actuators and indicators. Metal holders are automatically grounded by their fastening screw,
but a grounding stud can also be fitted.
