1/ Circuit breakers shall not trip at 100 percent rated current but must trip at 125 or 150 percent of rated current. Between 100
percent and 125 or 150 percent, they may trip. Instantaneous is defined as less than 15 milliseconds.
2/ High-inrush test shall be performed using one alternation, which has a peak value of 1,800 percent of rated current. 400 Hz
and dc delays shall be subjected to a 400 Hz waveform, 60 Hz delays shall be subjected to a 60 Hz waveform.
3/ High and low test temperature tolerances are ±2°C.
