Geya - Model DC ACB GYW3 - DC Air Circuit Breaker (ACB) - Brochure

It has a number of invention patents for the design of circuit breaker arc-extinguishing chamber andcontact system. Using the principles of narrow slit, air blowing, and magnetic blowing arc extinguishing,optimizing the shape of the arc extinguishing grid and the layout of the arc extinguishing grid, increasingthe driving force for the arc, reducing the resistance of entering the arc extinguishing chamber, andimproving the breaking capacity of the product,and realize reliable arc extinguishing lower than DC1500V.The time for the controller to collect signals and issue commands is optimized, and when a large faultcurrent occurs, the total breaking time can be greatly shortened.
