An automatic transfer switch is an electrical device that switches a load between two sources as soon as it senses a loss of power. These units are particularly useful on backup generators as they will start up as soon as the main power source fails. The automatic transfer switch can also start a backup generator if it senses voltage fluctuations. It will automatically disconnect the main power supply when the generator switches on. When the power comes back on the automatic transfer switch will turn the generator back off. Some transfer switches can prioritise certain circuits that are essential and route the power to them only. The switch can be set by the user to comfortable cover all their requirements.

The unit can be safely stored at -20 degrees Celsius up to a temperature of 70 degrees Celsius. The automatic transfer switch has a maximum current of 1600 Amps and a maximum voltage of 220 or 389 Volt. The transfer time is 0.45 seconds. The unit is an integrated type with self input and self recovery function. The units are ISO9001:2008 and have passed the EMC IEC6100-4 electromagnetic compatibility test. It is a 3 phase automatic transfer switch.
Benefits of using the YES1 – 100GA 4 pole automatic transfer switch
The unit is compact and well made. You will never have a situation where you are without power and no matter whether you are on site or off the ATS will make sure you have power to all your necessary machinery at all times. When the power supply fluctuates it can switch the generator on and off with only a short cool down period. The transfer switch isolates the generator from mains power when the generator is on. This is to ensure that there is no feedback into the mains line.
