ActronAir Indoor Evaporator EC Plug Fan SC560F5 560mm 3-Phase is a 560mm EC plug fan from the SC series range for commercial indoor units, providing EC variable-speed airflow as an alternative motor platform to the K3G series for systems specifying the SC560F5 configuration. The SC560 and K3G560 series use different electrical interfaces and 0-10V control inputs -- confirm the factory-fitted motor model from the unit service label before ordering to avoid an incompatible replacement. Isolate power at mains before replacement -- EC motors and variable drives retain dangerous residual voltages for up to 5 minutes after power isolation.
