product guide：

TKQ3 series automatic transfer switches are suitable for AC50HZ ,rated voltage 380V, DC rated voltage up 220V,rated electric current to 1600A.The switches are used in the infrequent on and off circuit.

function trait：

Performance characteristics:
1.Full electrical engineering integrity which allows auto-control without external controller
2.The world high-tech logic control circuit with strong anti-jamming and no environmental interference.
3.The mechanism with spring powered accumulator applied in the switch main body, which allows for zero electrical arc by the feeler connection and disconnection.
Standard compliance

◆ GB/T 14048.3-2002 《Low Switch Voltage Equipment and Control Equipmen,Switch, Isolation,Isolation switch, and Combined Electric Equipment of Fuses》.
GB/T14048.11-2002 《Low voltage switchgear and controlggear part6-1:Multiple function equipment automatic transfer switching equipment》.
Operation Emvironment :
1.Height above sea level does not exceed 2,000m;
2.Anbient temperature is not higher than 40℃and not lower than -5℃;
3.Relative humidity is not larger than 95%;
4.No eTKlosive dangerous medium environment;
5.No rain and snow attack environment;
(Note:if the load isolation switch is eTKected to be used in the conditionth at the ambient temperature is higher than +40℃ or is lower than -5℃-45℃,customers should inform to the manufactory.)
◆The products have three poles, four pole , and (three poles + on and offneural pole)
◆Current grades can be divided into 100A、160A、250A、630A、1000A、1250A、1600A.
◆3 control modes(R、B、C)
◆R、Municipal power supply- Municipal power supply, automatic change and automatic recovery, protection of missed phase.
◆B、125A up to 630A Municipal power supply-Municipal power supply,automatic change and automatic recovery, over voltage or lower-voltage function.
◆C、Municipal power supply-oil generator, automatic change and automatic recovery.Having the functions of over-voltage or lower-voltage of phase shortage protection and frequency detection.
◆The switches can be padlocked to keep the position status.
◆Use key switch to select operation.
