400A, 630A, 800A, 1000A Automatic Transfer Switch For Generator Part


Automatic Transfer Switch (ATS) is used which operation voltage is no more than 660VAC, and may transfer with load. The ATS rated current series is 40A, 63A, 80A,125A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A to 4000A, be divided up two types with 3 poles and 4 poles. The ATS of 40~125A is defined with ‘N’; 160~400 is defined with‘T’; 630A~2000A is defined with “M”. Above 2000A is also available.

Automatic Transfer Switch can automatically transfer load from mains power to emergency power without operator intervention. When mains power fails or voltage drop below 80% of normal voltage, the ATS will start emergency generator, after a preset time of 0 to 10 seconds(adjustable). At rated speed, the ATS will transfer load to emergency power with available size ranging from 40A to 4000A. There is a switch suitable for every project’s need.

ATS is an integral part of the power generation process, allowing smooth and immediate transfer of electrical current between multiple sources and the load. When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility's system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation.

The transfer switch senses when utility power is interrupted, and starts up the generator if the utility power remains absent. In about five to ten seconds, when the generator is producing full power, the transfer switch disconnects the load from the utility and connects it to the generator, restoring electricity to the load. The transfer switch continues to monitor utility power, and when it is restored, switches the load from the generator back to the utility. Once the generator is disconnected, it goes through a cool-down routine and is automatically shut down.

Choosing the right ATS for the generator set

1. Generator Set Current: =Genset KVA*1000/Voltage/1.732
2. ATS Size should be 120% of the generator set current.


Features:

1) For emergency power usage in building, auto transfer switch(ATS) is essential. ATS can auto transfer load from mains power supplying to emergency power.

2) When the main power supplying failure or voltage drop below 80% of normal voltage, ATS will auto start emergency generator set after a preset.

3) Time of 0 - 10 sec (adjustable according to the users). Once generator reach at rated speed, the ATS will transfer the load to emergency generator sets automatically.

4) The ATS has large variety current.
