Feature:1. Operation Mode: Double power automatic transfer switch can be operated automatically or manually, widely used in various places where continuous power failure is not allowed. Specially used for PZ30 power distribution box.2. Working Principle: When the automatic transfer switch works, when the normal power supply is abnormal, the standby power supply works immediately. When the normal power supply is turned on, it will automatically switch back to normal power supply from the standby power supply, ensuring a continuous and reliable power supply.3. Reliable Transmission: This automatic transfer switch is suitable for 50 or 60Hz AC rated 110V 100A emergency power supply system with compact structure, reliable transmission, standard 35mm rail mounting and easy installation and maintenance.4. Self Throwing and Self Returning: The double power automatic transfer switch is self throwing and self returning type with stable performance, widely used in families, factories, laboratories, farms, etc.5. PC and Silver: The changeover switch is made of flame retardant PC material, with good insulation and high temperature resistance, and silver contact anti aging, safe, reliable and anti interference.Specification:Item Type: Dual Power Automatic Transfer SwitchMaterial: PC, silverSwitch Type: Secondary power distributionRated Current: 100ARated Voltage: 110VACInsulation Voltage: 690VACRated Frequency: 50Hz 60HzElectrical Grade: PC grade isolation typeRated Impact Withstand Voltage: 8KVTouch Time: <50msOperation Conversion Time: <50msReturn Time: <50msClosing Time: <50ms.Package List:1 x Dual Power Automatic Transfer SwitchNote: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 352. 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 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
