View:1234567 Page

Scope of application
         FCQ3 series automatic transfer switching equipment (hereinafter referred to as the switch), apply to the AC 50/60Hz, rated working voltage 400V, rated current of 6A-1250A dual power supply system. Common power failure occurs, the change-over switch can automatically convert and backup power supply or generator to ensure the reliability and security of supply.
        Also need to load the selective conversion of two-way power. The product has the overload, short circuit, open-phase protection function. Especially suitable for fire protection, airports, radio and television, hospitals, shopping malls, banks, chemical, metallurgy, high-rise buildings and military facilities, and so does not allow power-off an important place, as to ensure the continuous supply of electrical equipment.
        The product complies with with IEC60947-6-1, and GB/T14048.11 standards.
