Miniature circuit breaker VA47-29 3P 4A 4,5kA C IEK

Преимущества

  • Two types of protection against overloads and short circuit.
  • Complete set of supplementary devices with the possibility of simple independent installation:
  • – State contact KS47;
  • – State contact KSV47;
  • – Undervoltage trip RMM47;
  • – Low-voltage release RN47.
  • Improved arc suppression system: extended service life, increased resistance to short-circuit currents.
  • Contact position indicator.
  • Wide operating temperature range from –40 to +50° С.
  • Simultaneous connection by FORK bar and flexible conductor is possible for power supply distribution via upper terminals, as well as connection by PIN bar.
  • New ergonomic design of ON/OFF lever.
  • Notched terminal clamps reduce the heat loss and increase mechanical stability of the connection.
