Feature 1 EASY OPERATION: This transfer switch supports automatic and manual operation, millisecond switching without power outage, widely used in various situation where continuous power outages are not allowed. 2 WORK PRINCIPLE: When there is an abnormality in the normal power supply, the backup power supply immediately operates, ensuring the good continuity, reliability, and security of the power supply. 3 WORK PARAMETERS: The rated voltage and current is AC110V 63A, with a frequency of 50/60HZ, the transfer switch is used for emergency power supply system, specifically designed for PZ30 distribution box. 4 DURABLE MATERIAL: The dual power transfer switch is made of flame retardant PC material, with good insulation, high temperature resistance, silver contact, which is aging resistant, safe and reliable. 5 WIDE APPLICATION: Isolation type anti interference, self switching and self resetting, widely used in households, shopping malls, factories, laboratories, breeding farms, and other situations.Item Type: Transfer SwitchMaterial: PC, SilverRated Current Le: 63AInsulation Voltage Ui: AC690VRated Voltage Ue: AC110VFrequency: 50/60HzRated Control Voltage US: 110VAC 85%Us-110%UsLevel: PC LevelSpecification: 4PService Life: Electrical: 2000 Times; Mechanical: 5000 timesRated Short Circuit Current: 50kAFuse: RT16-00-63ARated Impulse Withstand Voltage: 8kVAuxiliary Circuit: 2 Relays, each with two sets of contact capacity: AC110V50HZ le=5yTouch Time: <50msOperation Conversion Time: <50msReturn Time: <50msClosing Time: <50msSize: Approx. 143 x 96 x 69mm / 5.6 x 3.8 x 2.7in Package List1 x Transfer SwitchNote1. The maximum ambient temperature shall not exceed 40, the minimum temperature 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 2000 meter3. 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, when the temperature is 25, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation on the surface of the product.
