Label:Yes
-Protective measure to avoid incorrect connection of the phase sequence of the L1, L2, L3 three-phase AC power supply. It acts instantaneously. The indicator light adopts a yellow light form.
-The protection functions of the monitor are not affected by the line or load current, inrush current, unbalanced current, or load characteristics. It can operate continuously with full performance under all climatic conditions. Its power consumption does not exceed 2W.
-Refers to protection against voltage imbalance that may affect the safe working of equipment. It is triggered when the voltage unbalance rate exceeds 8%. The indicator light form is: the red light for phase loss is on, and this indicator has priority.
-When a fault occurs, the monitor will initiate a delay of 1~2 seconds before the relay releases.
-Refers to the protection against phase failure of any phase when the protected equipment is in either an operating state or a non-operating state. The indicator light adopts a red light form and has priority.
Specification:
Model: TG30S
Voltage: 220-440V AC
Installation method: rail installation
Size:7.2*6.4*3cm(2.83*2.52*1.18in)
Working state:
1. L1, L2, L3 three-phase wiring is correct, the monitor green light is on, the relay is closed; if the phase sequence is wrong, the monitor yellow light is on, just exchange any two phases of L1, L2, L3 three phases, the monitor will Can recognize the phase sequence and work normally.
When the protected device is working normally, the yellow light is on, and when the relay does not pick up, it should be regarded as misconnection of the external line phase sequence, and the monitor has the function of avoiding misconnection protection;
2. When the L1, L2, and L3 phases are out of phase, the red light is on, the green light is off, and the relay is released; when the voltage is normal, the green light is on and the relay is closed;
3. L1, L2, L3 are connected to three-phase AC voltage, NO and COM are normally open contacts; NC and COM are normally closed contacts. Use wire to connect the terminal block directly.
Note:
The actual product color may deviate from the photo due to light.
There may be a slight deviation in the measurement of product.
