Automatic Transfer Switch

How does an automatic transfer switch work

The working principle of the dual power automatic transfer switch is simply the replacement of one common power(normal power) supply and one backup power (reserve power) supply. When the common power suddenly shutdown or breakdown , it is composed of one or several switching dual power automatic transfer switches and other necessary electrical appliances. Used to detect power circuits and automatically convert one power source to another.

What is the principle of automatic transfer switch selection?

According to classification:

According to the IEC-60947-6 international standard, automatic transfer switching appliances can be divided into two levels: PC class and CB class.

PC Class: It is capable of making and carrying normal and fault currents, but not for breaking short-circuit currents. When the load is overloaded, the power supply continuity can still be maintained. fast action time.

CB Class: Its main contacts can make and break short-circuit currents. It has the overload protection function for the load-side electrical equipment and cables, and can connect, carry and break short-circuit current, and disconnect the load when the load is overloaded or short-circuited.

According to current:

15a automatic transfer switch,20 amp automatic transfer switch,  30 amp automatic transfer switch, 50 amp automatic transfer switch are usually used for household power supply.

200a automatic transfer switch, 400 amp automatic transfer switch, 600a automatic transfer switch, 1200 amp automatic transfer switch are usually used for dual power supply for key loads such as fire protection in large buildings.
