Описание
SQ3M series automatic transfer switch is used for the two-circuit power system of AC 50 Hz and rated voltage up to and including 690V. It is able to actuate the automatic transfer between the normal power and reserve power, requiring no manual operation. This switch conforms to the clauses stipulated in the GB/T14048.11 Automatic transfer switching equipment. It is operating mechanism has reliable electric and mechanical interlock to prevent the normal power and reserve power being switched on at the same time.
Within the scheduled time after the voltage of normal power detected phase A and each phase is disconnected, the switch can make the load connect to the reserve power from the normal power, after the normal power is recovered, the load returns to the normal power state, while, the switch has the phase-failure protection function.

Scope of Application
2.Atmospheric conditions: the air should be clean, the relative humidity should not exceed 50% at +40ºC, higher relative humidity is permissible at lower temperature conditions, for instance, RH may reach 90% at +20ºC, but should take the condensation into consideration that may be caused by temperature change.
3. The altitude of the installation site should not exceed 2000m, it should be used indoors
4. The installation site should be free of strenuous vibration or impact, with no corrosion affecting the electric elements
5.If beyond the abovementioned conditions, please negotiate with the manufacturer when placing the order
6. If the switch is intended for offshore oil or nuclear power station, shall enter into an additional technical agreement
