Phase Failure Relay

Our main goal is to provide superior customer service by offering high-quality Phase Failure Relays. These relays, which are available in plastic sealed and flux proofed varieties, are appropriate for absorbing voltage fluctuations in the event of a phase failure relay. A group of seasoned professionals created our Phase Failure Relay while adhering to the standards and regulations established by the sector. Some of the key characteristics of our relays are high dielectric strength and an extended operational life.

Phase Failure Relay

It is our main motto to serve the customers with maximum satisfaction through supplying high quality Phase Failure Relay. Available in Plastic sealed and flux proofed types, these relays are suitable for bearing the voltage fluctuations in case of a power phase failure. Our Phase Failure Relay is made by a team of veteran professionals, following the norms and guidelines laid down by the industry. High dielectric strength and advance operational life are some of the salient attributes of our relays.


  • Manual switch function & Easy operation
  • Sturdy design with Competitive Price
  • Fastest Delivery Quality Product
  • Capacitor load up to 200uF
  • Creepage distance:8mm
  • Dielectric strength more than 4000VAC

Popularly called as Single phasing preventer, the Phase Failure Relay operates instantaneously and safeguard the motor under any of the following states:

  • When any one of lines to the motor is disconnected.
  • When the connections of motor are reversed in phase.
  • Unbalanced voltage supply.


  • Before dispatch, the relays are thoroughly tested to ensure their reliable operation in the application. All the relays are routine tested at 2Kv for 1 minute.


  • System : 415 V, 50Hz, 3Ph 
  • Voltage Variation : +10% and -20% of system Voltage
  • Auxiliary : 1 set of 1 N/o & 1 N/c
  • Relay contacts : Change over contacts 
  • Rating of relay contacts : AC - 220 VA (Inductive) or 400 VA (Resistive) or at 415 volts Max 5 amps.

415 V Phase Failure Relay

We are successfully engaged in providing a wide ambit of 415 V Phase Failure Relay. It is suitable for monitoring incoming 3- phase supply. This relay is simple to install and maintain. Moreover, provided relay is useful to give protection against any damage or defect which is caused by phase loss. 415 V Phase Failure Relay is available in various models and sizes at affordable prices. It is generally procured form the sourced market vendors. 

Phase Reversal Failure Relay

 We are indulged in providing a distinct stock of Phase Reversal Failure Relay in the market. It is suitable for monitoring incoming 3-phase supply from Mains. It finds the application for monitoring electricity distribution line. Phase Reversal Failure Relay measure the sequence of the phases when being switched on. It is also suitable to give protection to the motor from overheating. It increases the motor life by preventing the motor from rotating in the wrong direction.
