The Phase Sequence Relay is a new high-tech product that is applied to large-scale digital integrated circuits and transformerless designs. Highly versatile (3-phase 220V~380V ), ultra-small size, very beautiful appearance.

It detect the waveform and phase of the power supply by IC to judge whether the power supply is abnormal. In the reverse phase (anti-phase), three-phase voltage imbalance, phase loss and short-circuit when the inductive load such as motor is running, it  can quickly judge and output the relay , and its function is not affected by the circuit or load current, surge current, unbalanced current and load characteristics, achieving  long-term operation of full performance and full climate to normal and stable operation of the motor. It can be used to provide relay for various three-phase motors and other three-phase equipment such as refrigeration compressor, pump, fan, air compressor, elevator, injection molding machine.

Characteristics of :
1. Phase loss : It means that any phase occurs phase loss when the protected circuit is in running or stopping status. In this case, the red indicator light will be lighted and be priority.
2. Phase reversal : It is a acting immediately, which protects L1, L2, and L3 three phase against wrong connection sequence. In this case, the yellow indicator light will be lighted.
3. Voltage imbalance : While a of voltage imbalance rate &; 50%, the imbalance of three phase voltage will affect the safe running of the equipment. In this case that there is a phase losing, the red indicator light will be lighted and be priority.
4. Delay :When the fault happens, the monitor will delay 1~3 seconds to act and release.

Characteristics of working:
1. If the connection of L1, L2 and L3 phases are right, the green light of the relay illuminates and the relay closes. If they are wrong, the yellow light of the relay illuminates. Exchanging any two of them, the relay will accept the phase sequence and begin to work normally.
In this case that there occurs yellow light illuminated and relay unclosed after the protected equipment works normally, it should be a wrong connection of external circuit. The relay has a function of against wrong connection.
2. While any of these L1, L2 and L3 phases is phase loss, the red light is lighted with the unlighted green light and the released relay. While the voltage come back to normal, it will recover immediately with lighted green light and relay.
3. L1, L2 and L3 connect with three phase AC. NO, COM are normally open contact point and NC, COM are normally contact point. Use lead to connect terminal directly.
