TG30 Sequence Phase Relay 3 Phase Failure Phase Loss Protection 220-380 VAC Three Phase Voltage Monitoring Relay Tracking Relay A

Specification:

Phase sequence relay is a new high-tech product applied to large-scale digital integrated circuits and transformerless designs. Very versatile (three-phase 220V~380V), ultra-small size, very beautiful appearance.
It detects the waveform and phase of the power supply by IC to determine whether the power supply is abnormal. In the reverse phase (anti-phase), three-phase voltage unbalance, phase loss and short circuit when the inductive load such as the motor is running, it can quickly judge and output the protection of the relay, and its protection function is not affected by the circuit or load current, surge current, unbalanced current and load characteristics, enabling long-term operation of full performance and full climate to ensure normal and stable operation of the motor.It can be used to provide relay protection for various three-phase motors and other three-phase equipment such as refrigeration compressor, pump, fan, air compressor, elevator, injection molding machine.
Protection Features:
1. Phase loss protection: It means that any phase loss occurs when the protected circuit is in the on or off state. In this case, the red light will be on and have priority.
2. Phase inversion protection: This is an immediately acting protection, which protects the three phases L1, L2 and L3 against a wrong connection sequence. In this case, the yellow indicator light will light up.
3. Voltage Unbalance Protection: While protection against voltage unbalance rate >50%, the unbalance of three-phase voltage will affect the safe operation of the equipment.In this case where there is a phase loss, the red light will light up and will have priority.
4. Delay Protection: When the fault occurs, the monitor will delay 1-3 seconds before taking action and releasing.
Working Features:
1. If the connection of phases L1, L2 and L3 is correct, the green indicator light on the relay lights up and the relay closes. If they are wrong, the yellow relay indicator lights up. By swapping two of them, the relay will accept the phase sequence and start working normally.
In this case where there is a yellow light on and a relay not closed after the protected equipment operates normally, it should be a bad connection of the external circuit. The relay has a connection error protection function.
2. While any of these phases L1, L2 and L3 are in phase loss, the red LED is on with the green LED off and the relay released.As the voltage returns to normal, it will immediately recover with a green light on and a relay closed.
3. L1, L2 and L3 connect to three-phase alternating current. NO, COM are normally open contact points and NC, COM are normally closed contact points. Use the cable to directly connect the terminal.
