Item Type: Transfer Switch <br>Model: NLQ4-125 2P <br>Material: PC, Silver <br>Insulation Voltage: AC690V.50HZ <br>Rated Voltage: AC400V.50HZ <br>Rated Working Voltage: AC230V <br>Grade: PC <br>Specification: 2P <br>Service Life: Electrical: 2000 Times, Mechanical: 5000 Times <br>Rated Short Circuit Current: 50kA <br>Fuse: RT16-00-63A <br>Rated Impulse Withstand Voltage: 8kV <br>Control Circuit: Rated control VoltageUs: AC220V 85% Us-110% Us <br>Auxiliary Circuit: 2 relays, each relay has 2 groups of contact capacity: AC220V50HZ le=5y <br>Touch Time: <50ms <br>Operation Switching Time: <50ms <br>Return Time: <50ms <br>Closing Time: <50ms<br>1、EASY OPERATION: Dual power transfer switch, supporting automatic and manual operation, fast switching without power failure, ensuring stable and reliable transmission. <br>2、WORKING PRINCIPLE: When the normal power supply is abnormal, the standby power supply will work immediately, ensuring the continuity, reliability and safety of power supply. <br>3、GOOD PERFORMANCE: The transfer switch has the characteristics of good isolation, less interference, self switching and self resetting, stable performance, etc., safe and practical. <br>4、APPLICABLE SCENES: Specially designed for household rail installation, used for PZ30 distribution box, suitable for families, shopping malls, factories, laboratories, etc. <br>5、PLASTIC HOUSING: The switch shell is made of PC material, with good insulation, high temperature and aging resistance, and the silver contact can improve the conductivity.1. The maximum ambient temperature shall not exceed 40℃, the minimum temperature shall not be lower than ?5℃, and the average temperature within 24 hours shall not be higher than 35℃. <br>2. The altitude of the installation site shall not be higher than 2000 meter. <br>3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; When the temperature is ?5℃, the relative humidity is high, for example, the temperature is 25℃, and the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with the occasional condensation on the product surface.1 x Transfer&nbsp;Switch<p>1 x User Manual<br></p>
