The invention relates to an integrated thermomagnetic system bracket of a small circuit breaker, which comprises a static contact plate, a magnet yoke and a double-metal positioning piece. The magnet yoke is located between the static contact plate and the double-metal positioning piece. The static contact plate, the magnet yoke and the double-metal positioning piece are integrally structured. The magnet yoke comprises a conductive part and a magnetic inductive part. The conductive part is made of a metal conductive material and the magnetic inductive part is made of a ferro magnetic material. According to the thermomagnetic system bracket provided by the invention, the static contact plate, the magnet yoke and the double-metal positioning piece are integrally structured so that the number of parts is reduced, the stability of a magnet yoke magnetic field is enhanced, and the stability of a tripping mechanism of the circuit breaker is improved. At the same time, the cost of the magnet yoke is saved according to dual functions of the magnet yoke where current passes through and which generates the magnetic field, so that the thermomagnetic system bracket as a whole is simpler, and further, the defect that conventional bracket welding leads to deformation of the bracket can be avoided.
