调节整定电流时，瞬时脱扣电流应大于短延时脱扣电流，短延时脱扣电流应大于长延时脱扣电流。

When regulating current, the instantaneous tripping current must larger than the short time delay current must larger than the long time delay tripping current.

注：对CM1-160 、225四极断路器，其中性极（N ）的 瞬时 脱扣器（ 短路保护）均 无5In规格。

Note:For CM1-160,225 four-poles breakers, the instantaneous release of N-pole (short-circuit protection) have no 5 In spec.
