Automatic phase switch EXT10000202-WPL

APM-10 universal automatic phase changer. It is used to power a single-phase industrial or household installation 230 V / 50 Hz from a three-phase 4-wire network 3 x 400+N to ensure uninterrupted power supply to a single-phase electrical installation and protect it against unacceptable voltage fluctuations in the network. Depending on the presence and quality of the voltage on the phases, the APM-10 automatically selects the phase with the best parameters and switches a single-phase load of any power to this phase: when the power does not exceed 3.5 kW (16 A), the load is supplied directly from the APM-10; when the power exceeds 3.5 kW (16 A), the phase switch controls the coils of external contactors with the appropriate power (external contactor not included in the scope of delivery). Minimum and maximum voltage thresholds are set by the user. The device must be connected to a three-phase network.
