Earth Leakage Protection

Earh Leakage Protection is obtained by : Fitting a VIGI Module on the Circuit Breakers VIGI Module Earth Leakage Device for EasyPact CVS / Compact NSX Range Moulded Case Circuit Breakers

  • Compliance with Standards – IEC60947-2 appendix B, IEC 60255-4 and IEC60801-2 to 5 covering protection against nuisance tripping due to:
    • Transient overvoltages, lightning strikes
    • Switching of devices on the distribution system
    • Electrostatic discharges and radio frequency disturbances
  • Device can be equipped with multifunction aux contact of MCCB to remotely signal tripping due to earth fault
  • Self powered – “no aux supply required”
  • Instantaneous tripping at 30mA in less the 40ms for human protection
  • Direct acting device – no shunt / UV release required in MCCB
