3 Position 2 Pole 25A AC690V Rotary Cam Switch

Universal transfer switch LW30 isolating switch

1. Product introduction LW30 series transfer switches are mainly used in circuits with AC 50Hz rated working voltage below 440V and rated current below 63A. They are used as the main switch of ventilation equipment, air conditioning and water pump systems, and can also directly control small-capacity AC motors. The product complies with the standards GB/T 14048.3 and IEC 60947-3. LW30 series switches have complete specifications, and the current levels are 20A, 25A, 32A, 40A, 63A. Lw30 series switches have the advantages of small size, compact structure, strict material selection, good insulation, finger protection function, safety and reliability, etc. 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 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 24 hours does not exceed +35C: (2) The lower limit of ambient air temperature does not exceed -25C; (3) The altitude of the installation site does not exceed 2000m; (4) When the highest temperature is +40°C, the relative humidity of the air does not exceed 50 %, higher relative humidity is allowed at lower temperatures, such as 90% at 20°C. Special measures should be taken for occasional condensation caused by temperature changes.
