Hilitand Power Automatic Transfer Switch 400V 4P Changeover Circuit Breaker Grade Micro Generator Transfer Switch for Electrical Distribution Systems

NOTE: Low pollution level, no serious vibration and shock, no corrosive environment, no serious dust, no conductive particles and dangerous substances, no strong electromagnetic interference, This power automatic transfer switch is widely used in the installation and use of lighting circuits in office buildings, shopping malls, banks, stations, hospitals and high rise buildings with fire requirements. Come with short circuit, overload, under voltage, as well as fire, output and shutdown functions. , fire fighting power interface, DC1224V reliable, long distance double point, bring noiseless operation,, easy installation, simple operation, and, When the power supply fails (only test the normal A phase voltage and maintain the A phase voltage, only test the loss of voltage or phase loss, will automatically connect one or more load circuits from the power supply to another power supply to ensure normal power supply load. The power supply of the circuit ensures a good function, How to Use: 1. According to the circuit design, it is necessary to connect the public power supply and the backup power supply. Two circuit breakers are connected in parallel, but the phase sequence is the same; 2. If the circuit breaker is class 3, the neutral line must be connected to the 2and 4neutral terminals; 3. It should be checked before installation, and the product should be installed dry,,,,,.
