GAEYAELE W2R-3P Din Rail Mounted Automatic Transfer Switch Three Phase ATS 100A Power Transfer Switch (W2R 3P 100A)

I bought it, to use it with a 10000 watt generator that works 120/220 volts, in a beach house where we have many power outages, so far it has worked very well in making the transfer.  It looks or feels very good quality materials.   I have been very comfortable since I should not be going to each power drop to be moving manual switches.   Today, having a fall, I only turn on the generator with remote control and the ATS makes the change. When the energy arrives in the city, it only turns off the generator by remote control.  It is quick to make the change.

After reading the reviews I decided to test the unit on the Bench.It will automatically transfers to Generator using 110VACI tested transfer back to city power on 110 VAC it just buzzes.I tried testing transfer back to city power using 220vac. And it transferred over nicely.I am not shur what happens when bolth are active. But generator side uses 110Volts to transfer and the unit uses 220vac on the City power side to transfer.All on the little terminals.This way automatic functions should work.I have not installed yet. I just wanted to share what I found.Everything looks good. Also I agree it will not hold 2awg wire.

I wired the unit and attempted to transfer from grid to gen (inverter actually) and it buzzed loudly for about 5 seconds and began smoking. The automatic transfer is questionable. The manual transfer function does work. Unsure if I trust this product with an inverter to not melt down and cause a fire.

Basado en el costo del ATS vale la pena comprarlo, es importante cuando lo compre vea si su necesidad es MONOFASICA o TRIFASICA el que yo compre fue TRIFASICO y funciono como lo describe.

I have had this installed for a few months now, luckily never had to switch the generator power, but I like it, and the initial set up worked as expected. There are no directions to speak of, so I don't have the automatic feature functional. I just plan to manually switch it after I have started the generator.

Excelente artículo, como fue ofrecido

Only goes to generator supply as preferred, not City, even when City is active.Can only switch manually.When generator supply goes dead, won't switch back to City Supply even when City supply is available.Threw it away.

Instructions are minimal/lacking. Does not work with 110/120v. Do not believe comments that say it does.
