TVR20002 voltage phase sequence multifunction protector is also called threephase power monitor, phase sequence protector, overvoltage and undervoltage protector. Mainly used for AC 5060Hz, rated voltage below 460V, industrial threephase 220V, 380V, 440V, 460V and other voltage levels of various fault detection. Provides relay protection for high voltage, low voltage, phase loss, reverse phase (phase sequence), and threephase voltage imbalance of the threephase input power supply.
Features:
1. Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc.
2. Such as central air conditioning compressor protection, power monitoring of various elevators, phase loss of pumps and oil pumps, reverse phase protection, etc.
3. It is an indispensable protection product for the normal working voltage of the maintenance equipment in the operation of industrial equipment.
4. Installation method: The base of the protector adopts the rail type, and there are two M4 screw holes in the structure, which can be directly installed separately or installed on the HT35 rail.
5. Indicator light: Indicated by 5 indicators: normal, lack of phase (voltage threephase unbalance), reverse phase, overvoltage, undervoltage.
6. Phase loss protection: When the protected line is in the running state or nonoperating state, any phase failure occurs, and the delay is 2S.
7. Reverse phase protection: A protection measure to prevent L1, L2, L3 threephase AC phase sequence from being connected incorrectly, delay 2S action.
8. Voltage unbalance protection: It refers to a protection measure that the threephase voltage imbalance will affect the safe operation of the line. When the threephase unbalance rate x100percent >10percent , the protection delay 2S action.
9. Overvoltage protection: It means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC.
10. Undervoltage protection: It means that the voltage of the protected line is lower than the set value, the delay is 3~8S, and the recovery is 3~20VAC.

Note:
1. Since this protector is only protected against voltage and its phase sequence, it can be applied to motors of various powers.
2. This product is generally sampled on the power side of the threephase power supply and must not be installed on the output side of the variable frequency current.
.Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, electric control boxes, power distribution cabinets, cranes, etc.
It is an indispensable protection product for the normal working voltage of the maintenance equipment in the operation of industrial equipment.
Indicator light: Indicated by 5 indicators: normal, lack of phase (voltage threephase unbalance), reverse phase, overvoltage, undervoltage.
Overvoltage protection: It means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC.
Undervoltage protection: It means that the voltage of the protected line is lower than the set value, the delay is 3~8S, and the recovery is 3~20VAC.
