The carrier module is installed on one side of the molded case circuit breaker in a split mode, and the installation mode is as follows: the trapezoidal lug of the carrier module is inserted into the dovetail groove of the side wall of the base, the carrier module and the base are limited in the horizontal direction, the upper cover is installed on the base, and meanwhile, the carrier module is crimped, so that the carrier module and the molded case circuit breaker body are limited in the vertical direction, the wiring of flat cables between the main controller and the carrier circuit board is facilitated at the positions of the first opening and the second opening, the wiring distance is shortened, and the installation is facilitated. The utility model discloses thing networking circuit breaker adopts split type carrier wave module and moulded case circuit breaker body to realize convenient installation location, makes carrier wave function module and moulded case circuit breaker's control circuit keep apart completely, improves thing networking moulded case circuit breaker safety in utilization performance and reliability.

The utility model discloses further set up to form at least one support column on carrier wave module is close to the lateral wall of moulded case circuit breaker body, the support column sets up in one side or both sides of trapezoidal lug, the lateral wall of base just forms the draw-in groove to the position of support column, and the draw-in groove setting is close to the side of upper cover at the base, the support column is connected in the draw-in groove, the same crimping of support column is between upper cover and base.

The supporting column can further improve the positioning of the molded case circuit breaker body and the carrier module.
