They can also be used for infrequent line switching under normal circumstances. Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise, and residential buildings. In existing miniature circuit breakers, multi-pole circuit breakers are usually connected in series to increase the system voltage. To prevent interphase short circuits, an insulating plate is required between the housings of two adjacent circuit breakers. However, existing insulating plates are mostly fixed with multiple screws, which is relatively troublesome to install and remove. Based on this, the utility model proposes an intelligent circuit breaker housing. This circuit breaker housing uses main and auxiliary partitions for insulation protection. The partition is connected to the circuit breaker outer plate by a snap. The arc-shaped extended edge is pressed to further tightly connect the partition to the two circuit breaker housings, making it easy to disassemble and providing insulation protection, effectively preventing interphase short circuits in the circuit breaker.
