Feature:1. SILVER CONTACT: The contacts in the automatic transfer switch use silver contacts, which can greatly improve the conductivity and service life of the product.2. PC SHELL: The shell is made of safe flame retardant PC material, which has good insulation, high temperature resistance and anti aging.3. FAST SWITCHING: When there is an abnormality in the normal power supply, the backup power supply will work immediately, and the switch will not power off to ensure continuous, safe and reliable power supply.4. DIN RAIL TYPE: This transfer switch is specially designed for track installation and is specially used for PZ30 distribution box. When the normal power supply is abnormal, the standby power supply will start working immediately.5. WIDE RANGE OF APPLICATION: This switch is mainly used to test whether the main power supply or backup power supply is normal, and is widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, etc.Specification:Item Type: Dual Power Automatic Transfer SwitchMaterial: PC, silverModel: CHLT 63/4PInsulation Voltage: AC690VRated Voltage: AC400VCoil Voltage: 220VACLevel: PC levelSpecifications: 4PLife: Electrical: 2000 times; Mechanical: 5000 timesRated Short Circuit Current: 50kAFuse: RT16 00 63ARated Impulse withstand Voltage: 8kVControl Circuit: Rated control voltage Us: AC220V 85% Us-110% UsAuxiliary Circuit: 2 relays, each with two sets of contactsCapacity: AC220V50HZ le=5yTouch Time: <50msOperation Transition Time: <50msReturn Time: <50msOff Time: <50ms.Package List:1 x Dual Power Automatic Transfer Switch1 x InstructionNote:1. The maximum ambient temperature should not exceed 40C, the minimum should not be lower than 5C, and the average temperature within 24 hours should not be higher than 35C2. The altitude of the installation site should not be higher than 2000m3. When the maximum temperature reaches 40C, the relative humidity of the installation site should not exceed 50%, when the temperature is the lowest temperature of 5C, the relative humidity is higher, for example, if the temperature is 25C, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes.
