1.Application
The LW26 series rotary switch mainly applies to 400v and below, AC 50Hz or 240V below DC circuits. For breaking and closing, change-over of circuits under unfrequently manual operation. And the typical application are: control switch of 3 phase motors, control switch of switch gear, control switch of instruments, and change-over switch of machinery and welding machine.
The series comply witch the IEC 60947-3, IEC 60947-5-1.
The LW26 series have 8 current ratings:10A,20A,25A,32A,63A,125A,160A and 315A.
The Lw26series rotary switch were designed for multiple functions, wide variety of applications.
The Lw26-10, LW26-20, LW26-25, and LW26-32F have finger protection terminals.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box for 20A,25A,32A and 63A.
2.Working condition
Ambient temperature do not exceed 40ºC, and the average temperature, measured over a period of 24 hours, do not exceed 35ºC.
Ambient temperature should not be below 25ºC.
Should Not be installed over 200m above sea level.
The humidity should not exceed 50% when the ambient temperature is 40ºC and higher humidity is allowed for lower temperature.
