[0004] However, the intelligent universal circuit breakers currently on the market are not easy to install and are also difficult to disassemble.

[0005] The Chinese utility model patent with application number 202021136832.3 proposes an intelligent universal circuit breaker. Although it can solve the above problems, it still has certain shortcomings:
