The base 1 is fixed on the housing 4 of the circuit breaker. The two ends of the base 1 and the controller 2 are connected by a bracket, which are the first bracket 5 and the second bracket 6 respectively. The radiator 3 is fixedly installed on the base 1. One end of the first bracket 5 and one end of the controller 2 form a plug-in fit and are fixed by screws at the plug-in connection. The screws are connected along the plug-in direction of the first bracket 5 and the controller 2 to form a reliable fixation between the first bracket 5 and the controller 2, especially to prevent the two from moving relative to each other in the opposite direction of the plug-in, thereby improving the connection effect. The other end of the first bracket 5 is connected and fixed to the base 1. Transferring the installation position of the radiator 3 to the base 1 can simplify the structure of the first bracket 5 and facilitate the connection and assembly of the first bracket 5 and the controller 2. The two ends of the second bracket 6 are respectively connected and fixed to the bottom of the base 1 and the other end of the controller 2 by self-tapping screws.
