RDQH5 (RDXQ5) Series Automatic Generator Transfer Switch Electric Equipment

RDQH5 series Automatic Transfer Switch (ATS) is applied to Power-system of AC50/60Hz, Rated operate voltage 400V, Rated operate current from 16A up to 630A. Normal, Backup interline of product can connect with Net-grid or one with Net-grid and another with generator power-supply. When one line has faults (phase-loss, overvoltage,undervoltage), ATS switches another circuit into line automatically for keeping the power-supply. It is mainly applied to important places, like high building, mall, bank, hospital, airplane, etc., which not allowed power-off. And ATS has short-circuit, overload protection to ensure the reliability and safety of power-supply.
Standard: IEC/EN 60947-6-1, GB/T 14048.11
