1.Application Dual Power Automatic Transfer Switching Equipment Rated operating voltage:400V. Rated current: under 63A SKATS-Q3/4P is terminal type automatic transfer device. It’s suitable for 3 phases 4 wires (or 1 phase 1 wire) dual power grid with AC 50/60Hz, rated voltage 400V/230V and rated current up to 63A. When one power goes wrong (only test normal Phase A voltage and reserve Phase A voltage, only test loss voltage or loss phase),it will automatic connect one or several load circuits from one power to the other power automatically, to ensure normal power supply of load circuits. The automatic transfer switch conforms to IEC60947-6-1 and GB/T14048.11 2.Normal conditions for operation and installation: Environmental Temperature Condition:-5~+40°C Installation site is not more than 2000 meters above sea level. Pollution Level: Grade 3 Installation Category: 3 Vertical installation or horizontal installation
