Table 1 Tripping characteristics(Reference temperature 30℃)
| Test | Curve | Test current ln(A) | Status | Time limit for tripping or non-tripping | Expected result | Remark |
| a | B,C,D | 1.13ln | Cold | t≤1h | Non-tripping | Current smoothly rises to specified value within 5s |
| b | B,C,D | 1.45ln | Following item a test | t<1h | Tripping | |
| c | B,C,D | 2.55ln | Cold | 1s<t<60s(ln≤32A) 1s<t<120s(ln>32A) |

| d | B C D |
3ln 5ln 10ln |
Cold | t≤0.1s | Non-tripping | Switch on the power supply by closing the auxiliary switch |
| e | B C D |
5ln 10ln 20ln |
Cold | t<0.1s | Tripping | Switch on the power supply by closing the auxiliary switch |
Note: The term "cold " means that the test is carried out at a reference calibration temperature without load before the test.
