Earth Fault Relay Three Phase

Mounting Type : DIN Rail Mounting
An Earth Fault Relay is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

  • Aux. Supply: 3 Phase, 415 VAC +-10%
  • Mounting: Din Rail
  • Base mounting dimensions: 55 (W) x 65 (H) x 125 (D) mm.
  • Output: Two Potential free Relay contact of 5A rating
  • UV: UV Setting 360 to 400 V Default is 360 v
  • OV: OV Setting 430 to 460 V Default is 450 v
  • UB: Unbalance Voltage Setting 30to 100 V Default is 60 v
  • DLY: Relay on Delay Setting 1to 10 sec Default is 10 sec
  • TRP: Fault trip delay setting 1 to 10 sec defoult is 5sec
  • RP: Reverse Phase Enable setting Yes to No defoult is Yes
  • E-N: Earth to Neutral Voltage setting 1 to 30 V difoult is 0 V


  • Relay trip for Earth-Neutral voltage fault.
  • Earth fault voltage range selectable from 1 to 300 Volt.
  • Indication of earth fault by message on display.
  • Over voltage & under voltage set points site selectable.
