D11 Series Changeover Rotary Cam Switch

D11 series is series transfer switches are mainly used in electrical circuits with AC 50Hzz rated working voltage below 440V, and rated current up to 63A. They are used as main switches for ventilation equipment, air conditioners and water pump systems, and can also directly control small-capacity AC motors. The product conforms to the standard GB/T 14048.3 and IEC 60947-3. The LW30 series switches are complete in specifications, with current levels of 20A, 25A, 32A, 40A, 63A. The Lw30 series switch has the advantages of small size, compact structure, careful selection of materials, good insulation, finger protection function, safety and reliability, and other contact blocks can be added to the 3-pole standard block without removing the switch. The insulation distance of Lw30 series switches is larger than that of other switches of the same type, and the disconnection speed is fast, which is suitable for DC switches. 2.Product Features (1)The ambient air temperature does not exceed +40°C. And the average temperature within 24h does not exceed +35C: (2)The lower limit of ambient air temperature does not exceed – 25C; (3)The altitude of the installation site shall not exceed 2000m; (4)When the maximum temperature is + 40°Cz the relative humidity of the air does not exceed 50%, and a higher relative humidity can be allowed at lower temperatures, such as 90% at 20°C. Special measures should be taken for occasional condensation due to temperature changes.
