The wiring of the circuit breaker is pre-board, post-board, plug-in, and drawer type. If there is no special requirement, the user will supply the board in front of the board. The pre-board wiring is a common wiring method.

(1) Post-board wiring: The rear-mounted wiring of the molded case circuit breaker is characterized by the ability to replace or repair the circuit breaker without rewiring, and only the front-end power supply must be disconnected. Due to the special structure, the product has been configured with special mounting plates and mounting screws and terminal screws according to the design requirements. It is necessary to pay special attention to the fact that the reliability of the contact of the large-capacity circuit breaker will directly affect the normal use of the circuit breaker. The medicine is taken seriously and installed strictly in accordance with the requirements of the manufacturer.

(2) Plug-in wiring: Molded case circuit breaker On the mounting plate of the complete set, first install a circuit breaker mount, 6 plugs on the mount, and 6 sockets on the circuit breaker's connection plate. There are bolts on the surface of the mounting bracket or the mounting bracket, and the power socket and load cable are connected in advance. When in use, insert the circuit breaker directly into the mount. If the circuit breaker is broken, just pull out the bad one and replace it with a good one. Its replacement time is shorter and more convenient than the front panel and the rear panel wiring. Because the insertion and extraction require a certain amount of manpower. Therefore, in China's plug-in products, the current of the frame is limited to a maximum of 400A. This saves maintenance and replacement time. Plug-in circuit breakers should be installed to check whether the plug of the circuit breaker is tightly installed, and the circuit breaker should be securely fastened to reduce contact resistance and improve reliability.

(3) Drawer type wiring: The input and output drawer of the circuit breaker is rotated clockwise or counterclockwise by the rocker. The molded case circuit breaker adopts the plug-in structure in the main circuit and the secondary circuit, omitting the fixed type. The isolator is used for one machine and two uses, which improves the economical use, and brings great convenience to operation and maintenance, and increases safety and reliability. In particular, the main circuit contact seat of the drawer seat can be used in common with the NT type circuit breaker socket, so that the fuse can be directly inserted into the power supply in an emergency state.
