Description: In 3TL7 Contactors, the low-voltage components are not arranged one behind the other (like 3TL6), but one above the other. This provides a slim design which can easily be mounted on the different switchgear and base frames. The high rated voltage of 24 kV opens a possibility for special applications in high voltage areas with a high number of switching cycles.
