[0025] In this embodiment, a molded case circuit breaker 1 and a mounting base 2 for mounting the molded case circuit breaker 1 are provided. Fixed blocks 3 are movably provided on both sides of the bottom of the molded case circuit breaker 1, and the two fixed blocks 3 are symmetrically arranged. A boss 4 is provided on the top of the mounting base 2, and a card plate 5 is provided on the top of the boss 4. The boss 4 grows on all four sides of the card plate 5. A card slot 6 is provided on the inner side of the two fixed blocks 3. The fixed block 3 and the card slot 6 are both "U"-shaped structures, and the card plate 5 is embedded in the card slot 6. A tension spring 7 is connected between the two fixing blocks 3. By placing the molded case circuit breaker 1 on the top of the mounting base 2 and pulling the two fixing blocks 3 to both sides respectively, the card plate 5 is placed between the two fixing blocks 3. After loosening the fixing blocks 3, the two fixing blocks 3 are pulled closer to each other by the tension spring 7, so that the card plate 5 is embedded in the card slot 6 to complete the installation of the molded case circuit breaker 1. By pulling the two fixing blocks 3 to both sides respectively, the card plate 5 is pulled out of the card slot 6, and the molded case circuit breaker 1 can be disassembled.
