Abstract

A contact device having a rotatable static contact (10) of a circuit breaker comprises a static contact (10) and a static contact support (40), wherein the static contact (10) is embedded into the static contact support (40), and a limiting component for limiting the static contact (10) from moving an axial position is arranged on the static contact support (40); the static contact (10) is capable of rotating around a central shaft (71) arranged on the static contact support (40), a static contact (10) spring for limiting the static contact (10) from rotating is arranged in the static contact support (40), and the static contact (10) spring and the static contact (10) are connected to fix the static contact (10). The static contact (10) of the device of the utility model is rotatably mounted on the static contact support (40), a repulsive force is generated on the contact to allow a moving contact and the static contact (10) to overturn at the same time, and then an electric arc is prolonged and arc blow-out is accelerated. The static contact (10) can be effectively prevented from moving axially along the shaft body through the limiting component formed on the static contact support (40), so as to ensure a contact area of the moving contact and the static contact effectively reduce assembling difficulty and improve assembling efficiency.
