- OUT OF PRODUCTION -

The relay type SIF is intended for the protection of electric lines and machines against overloads, shortcircuits and earth faults. The relay SIF5600 features the following principal characteristics:

  • three input measuring circuits for the line currents;
  • measuring circuit, provided with a band pass filter, for the residual current;
  • protection functions and final relays completely programmable by the user;
  • selectable operation curves with independent or dependent time as well for the overcurrent as for the earth fault function;
  • sequence of event logging;
  • optional blocking circuit, to perform accelerated protection schemes;
  • continuous monitoring of internal circuits;
  • serial communication circuit RS485 with MODBUS© RTU protocol;
  • CB Control (OPEN-CLOSE)with dedicated keylock switch
  • PC Window-based SW to ease relay setup, event and record retriving.
