Scope

LW28 Series Universal changeover switch mainly used for AC 50Hz,rated voltage upto 380V and below, DC voltage up to 220V, rated current to 160A electrical circuit formanually infrequent making or breaking the circuit for the purposes of cont rol andconversion ,can also controlling three-phase asynchronous motors and circuitdirectly as the purposes of master control and measurement. The products widelyused, instead of the various national switch, can be used as the circuit cont rol switch,measuring equipment switches, motor cont rol switches and the master controlswitch, and welding machine switch and so on.Compliance with standa rds: The changeover switch use to the main circuit switchingand direct control comply with GB14048.3-2001, IEC60947-3. The changeoverswitch use to master cont rol comply with GB14048.5 2001

Normal 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℃ the relative humidity reach condensation           occasionally due to temperature changes shouId take special measures.
