Rotary switches LW26 series
Application:
LW26 series changeover switch is used in the circuits of AC 50Hz,rated voltage up to 690V,DC voltage up to 240V,rated current up to 100A,to not frequently switch on/off electrical circuits, transfer and control circuits,also it can directly control small capacity motor or be used for master control or electric meters. The switch is used widely in circuit control,test equipment, switch for motor,master control,welding machine and etc.
Advantages: Small size. Multifunctin, compact structure, high quality material, good insulation, agile operation, reliability, safety, good apperance.
Current: From 5A to 160A.
Working Conditions:
1.Ambient temperature not more than 50℃,the average per 24 hours not exceeds 35℃
2.Lowest temperature not less than -25 ℃
3.The altitude not more tahn 4000m.
4.At highest temprature +50 ℃,the relative humidity not over 50%,at lower temprature,higher humidity is allowed,such as at 20 ℃,90% humidity allowed.It shall be adopt the special treatment against the condensation water.
Classification:
1.According to application, the switch divided into the types of changeover of main circuit,direct control motor,master control and measurement.
2.As per operating mode, it devided into positioned type, self-recover type,positioned self-recover type.
3. According to knots of contact system:The positioned type:1-12 konts (63A only has 8 konts),self-fecover type:1-3 konts,type of direct controling motoer:1-6 konts.
4. According to rotation angle:30°.45°,60°,and 90°.
5. According to figure of panel:square,rectangular,round types.
6. Classify according to opreating mode and combination position of opreating device ON.OFF.
