Описание

Two change-over contacts indicate the contact position of the S750 DR pole(s) independently and potential-free. A test button can be used to verify the correct indication of the contact position without switching the pole(s). The change-over contacts fulfill the requirements of electrical separation of the main circuit connected to the pole(s). The S750DR-AUX can be mounted on S750 DR 1-4 pole-devices without tools.
