Feature: 1. Automatic Transfer: When the normal power supply is abnormal, the switch will automatically switch to the standby power supply, making it work immediately. 2. Continuous Power Supply: This switch can be switched in milliseconds without interruption, which ensures the continuity, reliability and safety of the power supply. 3. Sturdy Construction: This automatic transfer switch has the characteristics of firm structure, reliable conversion, convenient installation and maintenance, and long service life. 4. Premium Material: The silver contact improves the conductivity and service life of the switch, and the flame retardant PC shell has good insulation, high temperature resistance and anti aging. 5. Wide Application: This switch can be widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, nurseries, etc. Specification: Item Type: Automatic Transfer Switch Material: PC and silver Model: CHLT 125 2P Insulation Voltage: AC690V Rated Voltage: AC400V Coil Voltage: 230VAC Level: PC level Specifications: 2P Life: Electrical: 2000 times Mechanical: 5000 times Rated Short Circuit Current: 50kA Fuse: RT16-00-63A Rated Impulse withstand Voltage: 8kV Control Circuit: Rated Control Voltage Us: AC220V 85% Us-110% Us Auxiliary Circuit: Two relays, each with two sets Contact Capacity: AC220V50HZ le=5y Touch Time: <50ms Operation Transition Time: <50ms Return Time: <50ms Off Time: <50ms. Package List: 1 x Automatic Transfer Switch1 x Instruction Note: 1. The maximum ambient temperature should not exceed 40℃, the minimum should not be lower than ‑5℃, and the average temperature within 24 hours should not be higher than 35℃2. The altitude of the installation site should not be higher than 2000m3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of ‑5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes
