Abstract

The invention relates to a breaker casing body structure. The breaker casing body structure comprises a casing body (1). The breaker casing body structure is characterized in that the casing body (1) comprises a front end face (101), a back end face (102), a left side face (103), a right side face (104), an upper surface (105) and a lower surface (106), wherein the right side face (104) is provided with an input port (104a), the left side face (103) is provided with a first operation port (103a), a first output port (103b), a second operation port (103a') and a second output port (103b'), the front end face (101) or / and the back end face (102) are provided with mounting holes (107), mounting guide ports (101a) are arranged above or / and below the mounting holes (107) at bottom portions of the front end face (101) or / and the back end face (102), and the upper surface (105) or / and the lower surface (106) are provided with positioning ports (106a). According to the breaker casing body structure, the whole layout is rearranged, so input / output ends are enabled to satisfy specific narrow space and volume demands, the whole conductive loop and interface demand path is the shortest, the size of a breaker is reduced, and the mounting cost of the breaker is saved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical equipment, and in particular relates to a circuit breaker shell body structure, which can meet the installation requirements of circuit breakers in narrow spaces. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, commonly known as "air switch", also refers to low-voltage circuit breaker. It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equ...
