TVR2000-1 phase failure relay can be used for all devices that is connected 3-phase electrically. Its protection functions cannot be affected by current intensity of circuit or load, impulse current, unbalance current and load characteristics. The relay is able to operate in long hours and work to its full capability and full climate to ensure the state of the motor is normal. Its power consumption is less than 1.5W.

This measures the highest voltage value when the device is over-voltage, and measures the lowest voltage value when the device is under-voltage. This relay has 4 LED indicators. 

● Phase loss protection

● Phase sequence protection

● Over voltage protection

● Under voltage protection

● Phase unbalance protection

Over/under voltage protection is according to the average voltage and needs 8 seconds’ confirmation.
