Phase Failure Relays

These relays are suitable for monitoring incoming 3-phase supply from Mains (Electricity distribution line). Being independent of load, they can be used for any HP/KW rating of load

Protections / Functions:

  • Phase Failure [Phase Loss/Single Phasing]
  • Phase sequence reversal
  • Voltage Unbalance
  • Under Voltage
  • Over Voltage

Monitoring Relays

These relays are best suitable for monitoring balanced or unbalanced supplies.

Protections / Functions:

  • Under/over Voltage
  • Under/Over Current
  • Under/Over Frequency
  • Reverse Power
  • Earth Fault/Ground Fault
  • Earth leakage

Motor / Pump Protection Relays

Protections / Functions:

  • Phase Failure [Phase Loss/Single Phasing]
  • Phase sequence reversal
  • Voltage Unbalance
  • Under Voltage, Over Voltage
  • Overload protection as per motor characteristics
  • No-load/dry running
  • Motor winding overheating
  • Over-current/Short circuit/locked rotor
  • Earth Fault
