    In particular, the Gotthard Base Tunnel (opened on 1 June 2016) uses 15 kV, 16.7 Hz electrification. Due to high conversion costs, it is unlikely that existing 15 kV, 16.7 Hz systems will be converted to 25 kV, 50 Hz despite the fact that this would reduce the weight of the on-board step-down transformers to one third that of the present devices.

    en.wikipedia.org/wiki/Recloser

    Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 A and fault currents from 1–16 kA. [7] [8] On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts.
