 Remark
a 1.05In Cold state t≤1h Not tripping
b 1.30In Right after test number a t＜1h Tripping The current is rising within 5s
c 7In Cold state t≤0.2s Not tripping
d 10In Cold state t＜0.1s Tripping

Note: The terminology”Cold state”means that the test is performed at the base calibration temperature with no load prior to the test.
