Manual Change Over Switch 1A~63A 1P~4P


Manual Change over Switch Application:
SQ3W-63 series automatic transfer switch is designed and developed by our company according to universal customers' requirements.

this switch uses dz47 miniature circuit breaker(improved type) as the actating element, is equipped with the new type control mechanism.

with the smallest volume among the similar products, it also has the functions like the fire control and power generation, and it is specially usded in the important power supply locations where the power failure is not allowed.


Manual Change over Switch Working conditons:

SQ3W-63 automatic transfer switch is the latest research and development of terminalAutomatic switching device, applicable to the exchange of 50Hz, rated voltage 400V / 230V;

Rated current to 63A three-phase four wire ( also can be used in a phase line ) dual power supplyNetwork, when a power failure occurs ( only for the detection of common A phase voltages and standby A phaseVoltage detection only, pressure loss and phase 1 will automatically one or several load circuit fromA power supply is connected to a power supply, so as to ensure the normal power supply load circuit.Products meet III ( 60947.6.1, GB / T14048.11 standard; standard.

In 2, the normal working conditions and installation conditions1) ambient air temperature: limit of + 40 degrees C, the lower limit for a 5 DEG c.:2) the location of the installation elevation of not more than 2000m.31 pollution grade 3;4) installation group is;5) installation conditions switch can be vertical or horizontal installation.
