Feature 12 Operation Methods: Automatic transfer switch can be operated automatically or manually to ensure the continuity of power supply, compact structure and reliable transmission. 2Continuous Power Supply: The automatic transfer switch operates so that when the normal power supply is abnormal, the standby power supply works immediately to ensure the continuity of power supply. When the normal power supply is on, it will automatically switch back to normal power supply from the backup power supply. 3Standard 35mm Rail Mount: This automatic transfer switch is suitable for 50 or 60Hz AC rated 110V 63A emergency power supply system, designed for home rail mounting and dedicated for PZ30 distribution box. 4Flame Retardant PC Material and Silver Contacts: The dual power automatic transfer switch is made of flame retardant PC material, which is well insulated and high temperature resistant, and silver contacts, which are anti aging and easy to install and maintain. 5Widely Used: The automatic transfer switch is anti interference, self throwing and self repeating type, used in various scenarios where continuous power failure is not allowed, families, shopping centers, factories, laboratories, farms, etc.Item Type: Double Power Automatic Transfer SwitchMaterial: PC, SilverRated Current Le: 63AInsulation Voltage Ui: AC690VRated Voltage Ue: AC110VFrequency: 50 60HZRated Control Voltage US: 110VAC 85%Us-110%UsGrade: PC GradeSpecification: 2PLife Span:Electrical: 2000 TimesMechanical: 5000 TimesRated Short Circuit Current: 50kAFuse: RT16 00 63ARated Impulse Withstand Voltage: 8kVAuxiliary Circuit: Two Relays, Each Relay Has Two Sets Of Contact Capacity AC110V50HZ Le 5yTouch Time: <50msOperation Changeover Time: <50msReturn Time: <50msClosing Time: <50ms .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x DualPowerAutomaticTransferSwitchNote1. The maximum surrounding temperature shall not exceed 40, the minimum shall not be lower than ‑5, and the average temperature within 24 hours shall not be higher than 352. The altitude of the installation site should not be higher than 2000m 3. When the maximum temperature reaches 40, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature ‑5, the relative humidity is higher, 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 surface of the product
