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

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。

These circuit breakers should have the long time-delay over-current devices on each polar whose rated value can be adjusted from 80% to 160%.

这些断路器应在每极上装有额定值从80%至160%可调的长延时过电流装置。
