Visual fault signalling.
- Universally applicable
serially connected SPD for all types of LV electric and electronic equipments
against surge voltage.
- Installation to LV
installations, close to protected equipment.
- For protection of the equipments against impact of induced overvoltages during a lightning strike or switching overvoltages.
