S751DR-K20

General Information

  • Extended Product Type:
    S751DR-K20
  • Product ID:
    2CDH781010R0487
  • EAN:
    4016779879071
  • Catalog Description:
    S751DR-K20 Selective Main Circuit Breaker
  • Long Description:
    Selective main circuit-breakers of the S 750 DR series are SMCBs based on DIN VDE 0641-21 with voltage-independent operating principle. This means that they do not rely on a control circuit to make or break contact (SHU) and are therefore particularly suitable for use in energy distributionsystems with maximum availability requirements. They offer total selectivity to downstream MCBs and outstanding selectivity to upstream protective devices due to unique current limiting selectivity.
