IT300 load switch is medium voltage switchgear produced by France SDCEM for power plant project with bigger short-circuit current,which has advanced design, large thermal short-time withstand current, and simple structure. However, there are some problems in use due to the less actual usage of this product, some more serious. The equipment structure and movement principles of IT300 and the fault causes of an explosion of IT300 were analyzed, and some considerations and suggestions were also presented in the device hand-over, operation and maintenance.
