Based on the above example of the present application, the circuit breaker having the transformer assembly 100 may be less likely to be disturbed by external vibration or shaking, with higher safety and service life. Specifically, the base 200 may mount the transformer assembly 100, and the transformer assembly 100 is assembled, specifically, through the assembly slot 210 on the base 200. The transformer bracket 110 is used for supporting the transformer main bodies 120, each placing cavity 111 can be placed into one transformer main body 120, and the wire outlet groove 112 on the transformer can lead wires on the transformer main body 120 out and be connected to a corresponding circuit board. The first positioning portion 115 in the placement cavity 111 may be positioned with respect to the second positioning portion 121 on the transformer body 120, so that the transformer body 120 may be accurately mounted to a corresponding position in the placement cavity 111 with less degrees of freedom. The positioning protrusion 130 may improve connection stability of the transformer assembly 100. Wherein, the first protrusion 131 may improve connection stability between the transformer bracket 110 and the assembly groove 210, and the second protrusion 132 may improve connection stability between the transformer bracket 110 and the transformer body 120. The positioning protrusion 130 can prevent vibration mechanical damage and unnecessary noise generated by looseness inside the corresponding equipment of the transformer assembly 100, so that the use safety is improved and the service life is prolonged.

The same or similar reference numbers in the drawings correspond to the same or similar components; in the description of the present application, it should be understood that, if there is an azimuth or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc., based on the azimuth or positional relationship shown in the drawings, it is only for convenience of describing the present application and simplifying the description, but it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and thus terms describing the positional relationship in the drawings are merely illustrative and should not be construed as limitations of the present patent, and specific meanings of the terms described above may be understood by those skilled in the art according to specific circumstances.

The foregoing is illustrative of the present application and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., which fall within the spirit and principles of the present application.
