TVR3812 (Phase failure relay ,over voltage relay)
Phase loss protection: 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.
Over voltage protection: It means the voltage of the protected circuit is higher than set value. In this case, the yellow indicator light will be lighted.
The protection functions of relay dont be affected by current intensity of circuit or load, impulse current, imbalance current and load characteristic. The relay could long term work under full capability and full climate. Power consumption is lower than 2W.
