(2) Valid tolerances with steady-state energized trip unit or trip unit energized by auxiliary power supply, tripping time ≥ 100 ms, temperature and
currents within operating limits. If these conditions are not guaranteed, the tripping time tolerance of ± 10 % will become ± 20%.

ANSI / IEEE C37-2 encoding.
(4)
Valid tolerance for frequencies in the range: fn ± 2 %. For frequency outside the range a tolerance of ± 5 % applies.
