DFS FANA and DHS FANA: Emergency switching-off with remote operator

The new DHS FANA from residual current protection expert Doepke combines a switch-disconnector with an emergency switching-off function and a remote operator – all within just five standard modules.

In electrical installations where an all-current sensitive residual current protective device (RCD) is already installed, it fulfils the requirements of DIN VDE 0100-723 for classrooms with experimental equipment.

If no all-current sensitive RCD is present, another new addition comes into play: the DFS 4 B SK FANA. This all-current sensitive residual current circuit-breaker meets the dual requirements of the installation standards in one compact device and additionally features a remote operator for manual reclosing.

The following applies to both devices: An integrated active auxiliary unit monitors the external emergency stop circuit. If a connected emergency stop button is pressed, the DFS FANA or DHS FANA completely and all-pole disconnects the connected system components and loads from the electrical supply.

This ensures reliable safety in schools, laboratories, research facilities and anywhere electrical circuits are used for experimentation.

To restore the power supply, there is no longer any need to leave the classroom or laboratory. Reclosing can be carried out easily and conveniently via the remote operator from a central location – for example, from the teacher’s desk – without having to walk to the distribution board.
