Class CB double power automatic transfer switches are based on two circuit breakers, together with a motor-drive unit with mechanical interlocking and a controller. The mechanical interlock between the two circuit breakers ensures that they do not close at the same time, while the controller monitors the status of the two power sources and controls the motor-drive unit to switch the power sources according to the preset conditions.
