1.The inverse time operating characteristics of power distribution circuit breakers when all poles are energized simultaneously at anambient airtemperature of +40℃(with no humidity compensation)are shown in the following table:
| Test current designation | Setting current multiple | Conventional time | Initial state |
| In≤63 In > 63 | |||
| Conventional non-tripping current | 1.05 | ≥1h ≥2h | Cool state |
| Conventional tripping current | 1.30 | <1h<2h | Hot state |
2.The inverse time action characteristics of circuit breakers for motor protection without humidity compensation when all poles areenergizedsimultaneously at an ambient air temperature of +40℃ are shown in the following table.
| Test current designation | Setting current multiple | Conventional time | Initial state |
| In≤800 | |||
| Conventional non-tripping current | 1.0 | ≥2h | Cool state |
| Conventional tripping current | 1.20 | <2h | Hot state |
3.Action characteristics under short-circuit condition:The short-circuitcurentsetting value of the instantaneous tripper of the circuitbreaker for power distribution is 10ln.
The short-circuit current setting value of the instaneous tripper of the circuit breaker for motorprotection is 12ln.
The accuracy of the short-circuit curent setting value of the instantarheous tripper is 20%of the short-circuit currentsetting value.
