The relationship between small external circuit breaker and

In terms of functional theory, there is an interchangeable relationship between the two; the solution provider for small external circuit breakers is indeed promoting the implementation of this solution; but from the current industry general film recognition, it is not very high; Mainly reflected in the cost and reliability; the external circuit breaker is currently around 80; and the magnetic retention is the most expensive at around 10; the external circuit breaker is also very large; because of the many parts, the reliability is actually much lower than the magnetic retention ; The only advantage is that it can realize leakage protection
