Introduction
For breaking and closing,change-over of circuits underunfrequently manual operation.And the typical application are:control switch of 3phase motors,control switch of switch gear,control switch of instruments,andchange-over switch of machinery and welding machine.
The series comply with the GB 14048.3,GB 14048.5 and IEC 60947-3,IEC 60947-5-1.
The LW26 series have 8 current ratings
10A,20A,25A,32A,40A,63A,125A,160A250A,and 315A.They were designed for multiple functions,wide variety of applications.
The LW26-10,LW26-20,LW26-25,LW26-32F,LW26-40F and LW26-63F have fngerprotection terminals,
LW26 series rotary switch are an excellent substitute for LW2,LW5,LW6,LW8,LW12,LW15,HZ5,HZ10 and HZ12.
The LW26 series rotary switch has two derivatives,LW26GS Pad-lock type and LW26SKey-lock type.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box(IP65)for 20A to 250A.
Working conditions
- Ambient temperature DO NOTexceed 40℃,and the average temperature,measuredover a period of 24 hours,DO NOTexceed 35℃.
- Ambien temperature should not be below -25℃
- Should not be installed above 2000m above sea level.
- The humidity should not exceed 50%when the ambient temperaure is 40℃ and higherhumidity is allowed for lower temperature
Installation conditions
- A clean environment is required
- Please follow our manual
