Therefore, we manufacture and stock semi-finished products in which parts unrelated to the rating of the circuit breaker, such as the operation release mechanism, are installed in the case in advance, and depending on the requested rated current, we remove the overcurrent line related to the rated current from the electromagnetic coil. Since the circuit breaker can be installed and shipped at the final stage, it is easy to assemble the circuit breaker, and there is also the advantage that the management burden is small and the number of products in stock can be reduced.
