- 1/ Circuit breakers shall not trip at 100 percent rated current.  Characteristics A, B, C, D, H, I, K, L, M, and N must trip at 125 percent rated current; E, F, G, J, P, R, and S at 150 percent.  Any characteristic may trip between 100 percent and the must-trip value.  Instantaneous (Inst) is defined as less than 15 milliseconds. 

- 2/ Voltage, frequency, and tripping-time delay codes A, B, C, D, E, F, G, H, I, and J are standard delays without the high-inrush feature. 

- 3/ Voltage, frequency, and time delay codes K, L, M, N, P, R, S, and T incorporate the high-inrush or transient suppression feature. 

- 4/ 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 are subjected 

   - to a 400 Hz waveform, 60 Hz delays shall be subjected to a 60 Hz waveform. 

- 5/ High and low test temperature tolerances are 2C.
