Primary and secondary split type intelligent low-voltage molded case circuit breaker

The invention discloses a primary and secondary split type intelligent low-voltage molded case circuit breaker, which adopts a modular design supporting uninterrupted hot plug and uninterrupted hot plug and separates a primary part and a secondary part of the circuit breaker in a modular manner. The installation, maintenance and replacement of the low-voltage intelligent molded case circuit breaker are more targeted and scientific, and a maintenance plan can be arranged according to the service life of each component. According to the technical scheme that the internal modules can be rapidly and independently replaced, the production cost and the replacement cost brought by an existing molded case circuit breaker structure are reduced, the overall assembly efficiency is greatly improved, and unnecessary waste of manpower and material resources is reduced. Furthermore, a standby power supply mode is modified, a super capacitor is used as a standby power supply, and the requirements of industrial and power supp
