| Abstract: | Differential calculation method and traditional linear dimension chain calculation method were used respectively to calculate the reset rate of jump latch for moulded case circuit breaker （MCCB）. Based on it, dimension and tolerance of products were redesigned so as to ensure the reset rate meet the design requirements. The method has guiding significance to product tolerance distribution and plays an important role in improving the stability and reliability of the product. |
