Abstract： The double-break moulded case circuit breaker have good current limiting capability and advantages in power distribution and installation.The balance and stability of their contact systems are the keys to product structure design.In response to a double-break point contact system with simple structure and easy installation，combined with the mechanical analysis and simulation calculation，the system structure is optimized.A structure design concept is proposed，which features provide a stable contact，good pressure consistency and automatic balancing performance，and can realize the function of repelling and getting stuck.

Key words： double-break moulded case circuit breaker; contact system; contact pressure; automatic balancing performance
