Abstract
This utility model relates to the field of circuit breaker technology, specifically to a molded case circuit breaker. It solves the problem of difficult installation of the core support in existing circuit breakers, improving the practicality of the equipment. Its structure includes a housing, an inner mounting cavity, and several wiring slots on the outer side of the housing. A mounting slot is fixed to the side wall of the mounting cavity near the wiring slot. A core support is slidably connected within the mounting slot, and the core support is bolted to the housing. A connector is placed on the core support; one end of the connector is bolted to the bottom of the wiring slot, and the other end of the connector is located within the mounting cavity. This embodiment replaces the existing design of directly aligning the core support with the housing for installation. In this utility model, the core support and housing are directly positioned using the mounting slot, resulting in higher installation efficiency and greater practicality.
