TG30S

Characteristics of performance

1. The protection functions of relay don't 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.

2. There is no requirement for connecting method when it is used in protection of motor.

3. This product measures up GB/T 14048.1-2000,GB14048.5-2001 eqv IEC60947-1:1999.

4. The EMC of the product measures up the limits and methods of measurement of radio disturbance characteristics of GB4343-1995.

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 protection against wrong connection.

2. While any of these L1, L2 and L3 phases is Na phase, 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 closed relay.

3. L1, L2 and L3 connect with three phase AC. NO, COM are normally open contact point and NC, COM are normally closed contact point. Use lead to connect terminal directly.
