Feature:1. RELIABLE: The automatic switch not only supports automatic mode, but also can be operated by manual button, simple operation, reliable performance. When A power supply fails (only normal A phase voltage and standby A phase voltage are tested, only voltage loss or phase loss is tested), one or more load circuits are automatically connected from one power supply to another to ensure normal supply of load circuits2. MULTIPLE PROTECTION: Automatic transfer switches support many protection functions, including short circuit, overload, phase loss, undervoltage protection3. SAFE AND FLAME RETARDANT: Made of excellent flame retardant PC materials, possess good insulation, high temperature resistant, aging resistant, safe and reliable, using silver contacts can greatly improve the conductivity and service life of the product4. FOR HOUSEHOLD: The ATS has compact structure, reliable transmission, convenient installation and maintenance, long service life, can be installed vertically or horizontally, convenient and reliable power installation5. WIDE APPLICATION: Converts the common power supply to the standby power supply automatically or manually. The switch is mainly used in hospitals, shops, banks, chemical, metallurgy, high rise buildings, military facilities and other important occasion that do not allow power outageSpecification:Item Type: Dual Power Automatic Transfer Switch Material: PC and silverSeries: 2PInsulation Voltage: 4000 (V)Rated Voltage: 230 (V)ATS Product Category: CB micro breakConversion Time: Less than 3sOperating Frequency: 50 60HzRated Shock Tolerance Voltage: 4 (KV)3C Rated Voltage Range: 37V-230V.Package List:1 x Dual Power Automatic Transfer Switch1 x User Manual
