Phase voltage indicator SWN 3F


Phase voltage indicator SWN 3F

Power supply voltage indicator SWN 3F is intended for signalling the presence of voltage in a three-phase network. It is mounted on a TS 35 rail.

  • Each phase corresponds to one LED.
  • In the case of phase loss, the neon lamp associated with it will turn off. At lower voltage, the lamp glows fainter and turns off completely as voltage goes out.
  • Applications: low-voltage installations, intended for automation and control systems.
  • 5-year warranty, confirmed quality.
