Usage Tips:Feature:1. SIMPLE OPERATION AND RELIABLE: The automatic switch not only support 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 PROTECTIONS: Automatic transfer switch support many protection functions, including short circuit, overload, phase loss, undervoltage protection, safe and more stable3. SAFE AND FLAME RETARDANT: Dual power automatic transfer switch is 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 life4. 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: Convert the common power supply to the standby power supply automatically or manually. The automatic transfer 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 Switchmodel: NLQ5 125 4PMaterial: PC flame retardant and silverPole: 4PInsulation Voltage: 4000 (V)Rated Voltage: 400 (V)Working Voltage: 220 (V)ATS Product Category: CB micro breakConversion Time: Less than 2sOperating Frequency: 50 or 60HzRated Shock Tolerance Voltage: 4 (KV)Installation Method: Screw fixed.Package List:1 x Dual Power Automatic Transfer Switch1 x User Manual
