3X Phase Failure Phase Sequence Protection Relay TL-2238 leírása

1. Made of high quality material, durable and long service life.
2. Small body, perfect replacement for old or broken one, easy to install
3. The protective functions of relay don not be affected by current intensity of circuit or load, impulse current, imbalance current and load characteristic.
4. The relay could long term work under full capability and full climate, power consumption is lower than 2W.
5. This protect relay has phase loss protecting, phase opposite protecting, voltage imbalance protecting and delay protecting function.

Specification:
Condition: New
Item: Protect Relay
Characteristics of Working:
1. If the connection of L1, L2 and 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 unclose 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 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 close relay.
3. L1, L2 and connect with three phase AC. NO, COM are normally open contact point and NC, COM are normally close contact point. Use lead to connect terminal directly
Color: gray + black
