KBQ2 Intelligent Dual Power Automatic Transfer Switch consists of two three-pole or four pole molded case circuit breakers and their accessories, mechanical chain of transmission, intelligent controller and other components. Into a whole-and split the two structures. 
 Between the two breakers reliable mechanical interlocks and electrical chain protection, to eliminate the possibility of closing the two circuit breakers at the same time. 
 Intelligent controller is used for the control of the United States ATMEL microcontroller core, hardware simple, powerful, easy expansion, and high reliability. 
 The switch has a short circuit, overload, overvoltage, undervoltage, phase loss protection function and alarm function. Undervoltage value, closing time, opening time and other parameters can be set in the panel is free. 
 1. Two current conversion by an electromagnetic coil operation. 
 2. Simple structure, easy maintenance / 
 3. Contact capacity, the new shock bodies moving reliable, strong overload. 
 4. Eliminated the excess conductive parts, simple structure and long life.
