Tripping Characteristics(Reference Temperature: 30°C)
| Item | Test Current (A) | Initial Status | Time limit for tripping or non-tripping | Expected result | Remarks |
| a | 1.05In | Cold | t≤1h | Non-tripping | Current smoothly rises to specified value within 5s |
| b | 1.3In | Following item a test | t<1h | Tripping | |
| c | 2.55In | Cold | 1s<t<60s(In≤32A) 1s<t<120s(In>32A) |
Tripping | |
| d | 4In、8In、12In 80% |
Cold | t≥0.2s | Non-tripping | Circuit switched on by closing an auxiliary switch. Verifies rapid breaking capability. |
| e | 4In、8In、12In 120% |
Cold | t<0.2s | Tripping |
Note: The term “cold” means that the test is carried out at a reference calibration temperature without load before the test.
