1/ Circuit breakers shall not trip at 100 percent rated current. Characteristi cs
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 (In st) is defined as less than
15 milliseconds.
2/ Voltage, frequen cy, 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, frequen cy, 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 2C.

Circuit breakers covered by this specification sheet are substitutable for the manufacturer’s PINs as
shown below. This inform ation in no way implies that the manufacturer’s PIN is substitutable for the
military PIN.
