No. For the Sepam 40 ANSI 50N/51N protection function, the Harmonic 2 or H2 restraint percentage threshold is fixed at 20% plus or minus 5%.
This value has been set in the firmware and is based on simulations and studies of real events in power systems.
If you have a power system containing transformers with lower levels of the 2nd harmonic during energization, please contact Schneider Electric Technical Support for other solutions.
