[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal or abnormal circuit conditions. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. Circuit breakers are categorized as high-voltage and low-voltage based on their scope of use. The distinction between high and low voltage is often ambiguous, with those above 3kV generally considered high-voltage. A guide rail mount is a device made of grooves or ridges made of metal or other materials that supports, secures, and guides moving devices or equipment while reducing friction.

[0003] Currently, circuit breakers are installed by connecting the base to the DIN rail via screws. Although screw installation provides a more stable fixation, it is more troublesome to disassemble and cannot achieve quick disassembly and assembly of the circuit breaker. Based on this, the utility model proposes a circuit breaker base that is easy to install. The circuit breaker base adopts a combined structure consisting of a base plate, a heat dissipation support plate and a mounting plate. The heat dissipation support plate can fix the circuit breaker base using a clamping head, and a gap for heat dissipation is provided between the heat dissipation support plate and the base plate to meet the heat dissipation requirements of the circuit breaker. The heat dissipation support plate is connected to the guide rail via a mounting plate, and the mounting plate is connected to the connecting groove on the heat dissipation support plate via an elastic clamping platform, which makes the connection more stable. The overall structure does not require screws for installation, making the disassembly and assembly process more convenient. Utility Model Content
