Abstract

The invention discloses an intelligent plastic shell circuit breaker, comprising a plastic base and an upper cover, wherein, the base is provided with a contact mechanism, an operating mechanism, a tripping mechanism and a current transformer device; the upper surface of the upper cover is provided with an electronic operating switch and a display screen observation window; the operating mechanism comprises a switch-on and switch-off operating handle; the current transformer device comprises a current transformer, a substrate which is used for placing the current transformer and a cover body which matches with the substrate; the substrate is provided with a placement chamber which is used for placing the current transformer, an installation opening which is used for introducing the current transformer and a location boss which is used for locating the current transformer; the center of the location boss is provided with wiring holes; the cover body is provided with through holes which match with the wiring holes at the center of the location boss. The invention has the advantages of convenient installation and inspection operation.

Description

technical field [0001] The invention belongs to the technical field of low-voltage molded case circuit breakers, and in particular relates to an intelligent molded case circuit breaker. Background technique [0002] The existing intelligent molded case low-voltage circuit breaker generally has a display screen and an electronic operation switch on the upper surface of the upper cover. The electronic operation switch can be an ordinary toggle switch or a membrane button switch. It can be used to control the display screen display or to preset a certain current value range, and other such operations, etc. Since the electronic operation switch is exposed outside, it is easy to be damaged by bumping or misoperation, causing unnecessary losses, so there is a certain potential safety hazard, and its structure needs to be improved urgently. [0003] In addition, all intelligent molded case circuit breakers need to be equipped with a control circuit board. In traditional circuit br...
