earth-leakage protection relay earth-leakage protection relay - ELR-3F


  • Measured/monitored value:


  • Contact configuration:

    2 NO/NC

  • Other characteristics:

    differential, modular, DIN rail

  • Trigger voltage:

    24 V, 48 V, 110 V, 240 V, 415 V


The ELR-3F consists of two different setting values (current 0,03 or 0,5A / time 0,02 or 0,5 seconds) that enables you to choose the scampering current for the touch voltage values to be preserved below 50V according to the CEI 64-8 mark.

The ELR-3C series enables the right selection in case the ELRs or/and RCDs downstream or upstream need to be secured. The existing transmissions offer lifelong regulation of the Toroidal - ELR orbit. Any disturbance to this orbit can facilitate instant trip of security and enables you to recognize the anomaly without having a timely regulation done using a push button.

Additionally, the equipment is attached with filters at the input orbits which are resistant to outside interference, Pulse currents that have DC elements and adhere to the VDE 0664 and project IEC 23 Standards.
