Relais de courant compact X48DS

The X48DSA series earth leakage relays are designed to measure the leakage or unba-lance currents caused by conductors or appliances insulation losses and to react, in case the set limits are exceeded, switching off the power supply tothe defective system.

Main features and functions:

  • Wide range of trip currents and delays to guarantee the necessary selectivity in order to keep in operation the parts of the system not involved in the fault.
  • Three ranges of tripping current and delay to increase the setting accuracy.
  • Continuous check of the good connection with the toroidal transformer, performed on the measuring winding, with trip action in case of negativeresult.
  • Selectable manual or automatic reset.
  • Inputs for remote reset.
