Feature:1. MAIN PURPOSE: Dual power automatic switch is mainly used to test whether the main power supply or backup power supply is normal, rail mounting, dedicated to PZ30 distribution box.2. GOOD PERFORMANCE: The switch is suitable for 50 or 60Hz rated 400V AC emergency power supply system, with firm structure, reliable conversion, convenient installation and maintenance.3. APPLICABLE SCENES: Composed of transfer switch and controller, widely used in various situations that can not withstand power failure and can rely on electrical work or manual operation.4. EXCELLENT MATERIAL: Using flame retardant plastic, with good insulation, high temperature resistance, safe and reliable, and silver contacts greatly improve the conductivity of the switch.5. UNINTERRUPTED POWER: When the normal power supply is abnormal, the backup power will work immediately without interruption to ensure the continuity, reliability and safety of the power supply.Specification:Item Type: Automatic Transfer SwitchMaterial: PC, SilverInsulation Voltage: AC690VRated Voltage: AC400VCoil Voltage: 230VACLevel: PC LevelSpecification: 4PLifespan: Electrical: 2000 TimesMechanical: 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 Relay Has 2 Sets Of Contacts, Capacity: AC220V50HZ le=5yTouch Time: <50msOperation Transition Time: <50msReturn Time: <50msTurn Off Time Time: <50ms.Package List:1 x Automatic Transfer Switch1 x User ManualNote: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 352. The altitude of the installation site should not be higher than 2000 meters3. 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
