CDW3 series dual power automatic transfer switch is mainly composed of two CDW3 air circuit breakers, mechanical interlocks and dual power conversion controllers. It is suitable for 50Hz two-way, three-phase four-wire power grid with a rated working voltage of 400V. It can detect three-phase voltages simultaneously of two power supplies. When overvoltage or undervoltage (including open phase) occurs in either phase, it will automatically switch from the abnormal power supply to the normal power supply.
