GTQ3 series automatic transfer switch is applicable for distribution net work of AC50Hz,rated voltage of 400V, it has 3P and 4P.GTQ3 series automatic transfer switch is used in hospitals, hotels, market, post and communication fire high building, industrial assembly line by widely.
Electrical level: PC
Using: AC-33BÃ¯¼Ë† typical using: motor overload, resistance and less than 30% filament lamp overload )
Rated operating voltage: line voltage AC400V
Rated frequency: 50Hz, 60Hz
Overload (115% of rated current value ), under-voltage (75% of rated current value), lacking-phase or etc. of either power occurs, controller switch will automatically outputs through the other power.
The fixed delay time of switching is within 80s,the adjustable delay range of controller is 0-30s.
