50 vs. 60 Hz electro-mechanical 50/51 calibration

[sertec]

I've noticed some electrical-mechanical overcurrent(50/51) relays labeled 50/60 Hz and others labeled 60 HZ. We have been requested to calibrate several relays for 50Hz operation. Is there a consideration for 50 vz 60 Hz calibration of the same relay? We are in a 60Hz country.


Thank you.

figs. 10+ show L/C components, so, likely.

Depending on your test set, it may be possible to do the test at 50 Hz regardless of your supply frequency. This would be the preferred alternative, at least if I were your customer.
