LW28(LW39, LW26)Rotary Switch

LW28 LW39 LW26 Series Universal switch mainly for the exchange of 50Hz, rated voltage of 440V and below.Sunshine following DC voltage, rated current of the electrical circuits to 63A,not connected or breaking frequently for manual control and conversion circuits for also the direct control of three-phase asynchronous motor circuit as a master control and measurement purposes.Products are extensively used, instead of switching between different formal conversion, as the official switch control circuits, switching test equipment.motor control switches, and master control switches, and other switch welding machine.

Normal working conditions: 1.

Ambient air temperature does not exceed +40 , and the average temperature does not exceed its 24 C +35 C; 2. ambient air temperature does not exceed the limit of -5 C; 3. installation location at an altitude of less than 2000m; 4. maximum temperature of +40 C, the air temperature does not exceed 50% a lower temperature can allow a higher relative example, at 20 C up to 90%.

Dewing due to temperature changes occasional special measures.
