Earth Leakage Relays
Section available
in PDF format.
Click here to view...		 Earth Leakage Relays - We design and manufacture a number of multi function Earth Leakage Relays:

earth leakage relay; earth fault relay; ground fault relay;ground fault protection; core balance transformer; toroids.

These Earth Leakage Relays are supplied with various mountings:
  • The ELRM44 series with DIN rail mounting
  • The ELRP48 series 48 x 48 Panel mounting
  • The ELRV series DIN rail mounting
  • The ELR-IF series either DIN rail or surface mounting
  • The ELRF series with with DIN rail mounting
  • The Circular and Rectangular Toroid series
