1.General:   

 

      LW28 Series Universal changeover switch mainly used for AC 50Hz, rated voltage up to 380V and below, DC voltage up to 220V, rated current to 160A electrical circuit for manually infrequent making or breaking the circuit for the purposes of control and
conversion ,can also controlling three-phase asynchronous motors and circuit directly as the purposes of master control and measurement. 

      Compliance with standards: The changeover switch use to the main circuit switching
and direct control comply with GB14048.3-2001, IEC60947-3. 

      The changeover switch use to master control comply with GB14048.5-2001.             

 

 

2.Nomal working conditions:

1. The ambient air temperature does not exceed +40°C, the average temperature
within 24 hours and not more than +35°C.
2.The ambient air temperature is not lower than -5°C.
3.Installation site altitude does not exceed 2000m.
4.The relative humidity of the air no more than 50% when the maximum
temperature is +40°C and at a lower temperature allows a higher relative
humidity, such as when temperature is 20°C the relative humidity reach 90%.
   To condensation occasionally due to temperature changes should take special
measures.
