Feature: 1. 2 Operation Methods: Automatic transfer switch can be operated automatically or manually to ensure the continuity of power supply, compact structure and reliable transmission. 2. Continuous 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. 3. Standard 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. 4. Flame 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. 5. Widely 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. Specification: Item Type: Double Power Automatic Transfer Switch Material: PC, Silver Rated Current Le: 63A Insulation Voltage Ui: AC690V Rated Voltage Ue: AC110V Frequency: 50 60HZ Rated Control Voltage US: 110VAC 85%Us-110%Us Grade: PC Grade Specification: 2P Life Span: Electrical: 2000 Times Mechanical: 5000 Times Rated Short Circuit Current: 50kA Fuse: RT16 00 63A Rated Impulse Withstand Voltage: 8kV Auxiliary Circuit: Two Relays, Each Relay Has Two Sets Of Contact Capacity AC110V50HZ Le 5y Touch Time: <50ms Operation Changeover Time: <50ms Return Time: <50ms Closing Time: <50ms. Package List: 1 x Dual Power Automatic Transfer Switch Note: 1. 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 35℃2. 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
