Thermal Bimetal was the most important part of thermal release of miniature circuit breaker.The traditional design and selection was to select the model based on experience,and then select the model through making sample tests.The cycle was long and the cost was high.This paper proposed a thermal Bimetal thermal deformation simu-lation analysis and selection method based on Ansys.By comparing the thermal deformation of simulation analysis with the tripping stroke of mechanism,we selected the appropriate thermal Bimetal,and then conducted test verification.The re-sults indicated that the difference between simulation analysis and actual results was within 10%,which met the experi-mental requirements and had certain engineering application value.
